memory: remove IOMMU MR iommu_set_page_size_mask() callback
Everything is now in place to use the Host IOMMU Device callbacks to retrieve the page size mask usable with a given assigned device. This new method brings the advantage to pass the info much earlier to the virtual IOMMU and before the IOMMU MR gets enabled. So let's remove the call to memory_region_iommu_set_page_size_mask in vfio common.c and remove the single implementation of the IOMMU MR callback in the virtio-iommu.c

Retrieve the Host IOMMU Device page size mask when this latter is set. This allows to get the information much sooner than when relying on IOMMU MR set_page_size_mask() call, whcih happens when the IOMMU MR gets enabled. We introduce check_page_size_mask() helper whose code is inherited from current virtio_iommu_set_page_size_mask() implementation. This callback will be removed in a subsequent patch.

vdpa-dev: Fix initialisation order to restore VDUSE compatibility
VDUSE requires that virtqueues are first enabled before the DRIVER_OK status flag is set; with the current API of the kernel module, it is impossible to enable the opposite order in our block export code because userspace is not notified when a virtqueue is enabled.
This requirement also mathces the normal initialisation order as done by the generic vhost code in QEMU. However, commit 6c482547 accidentally changed the order for vdpa-dev and broke access to VDUSE devices with this.
This changes vdpa-dev to use the normal order again and use the standard vhost callback .vhost_set_vring_enable for this. VDUSE devices can be used with vdpa-dev again after this fix.
vhost_net intentionally avoided enabling the vrings for vdpa and does this manually later while it does enable them for other vhost backends. Reflect this in the vhost_net code and return early for vdpa, so that the behaviour doesn't change for this device.

virtio: use defer_call() in virtio_irqfd_notify()
virtio-blk and virtio-scsi invoke virtio_irqfd_notify() to send Used Buffer Notifications from an IOThread. This involves an eventfd write(2) syscall. Calling this repeatedly when completing multiple I/O requests in a row is wasteful.
Use the defer_call() API to batch together virtio_irqfd_notify() calls made during thread pool (aio=threads), Linux AIO (aio=native), and io_uring (aio=io_uring) completion processing.
Behavior is unchanged for emulated devices that do not use defer_call_begin()/defer_call_end() since defer_call() immediately invokes the callback when called outside a defer_call_begin()/defer_call_end() region.
fio rw=randread bs=4k iodepth=64 numjobs=8 IOPS increases by ~9% with a single IOThread and 8 vCPUs. iodepth=1 decreases by ~1% but this could be noise. Detailed performance data and configuration specifics are available here: https://gitlab.com/stefanha/virt-playbooks/-/tree/blk_io_plug-irqfd
This duplicates the BH that virtio-blk uses for batching. The next commit will remove it.

No functional change intended except for tracing, that now includes the (virtio) index being enabled and the return value of the ioctl.
Still ignoring return value of this function if called from vhost_vdpa_dev_start, as reorganize calling code around it is out of the scope of this series.

virtio-iommu: Fix 64kB host page size VFIO device assignment
When running on a 64kB page size host and protecting a VFIO device with the virtio-iommu, qemu crashes with this kind of message:

virtio-iommu: Fix 64kB host page size VFIO device assignment
When running on a 64kB page size host and protecting a VFIO device with the virtio-iommu, qemu crashes with this kind of message:
qemu-kvm: virtio-iommu page mask 0xfffffffffffff000 is incompatible with mask 0x20010000 qemu: hardware error: vfio: DMA mapping failed, unable to continue
This is due to the fact the IOMMU MR corresponding to the VFIO device is enabled very late on domain attach, after the machine init. The device reports a minimal 64kB page size but it is too late to be applied. virtio_iommu_set_page_size_mask() fails and this causes vfio_listener_region_add() to end up with hw_error();
To work around this issue, we transiently enable the IOMMU MR on machine init to collect the page size requirements and then restore the bypass state.

With TPM CRM device, vhost-vdpa reports an error when it tries to register a listener for a non aligned memory region:
qemu-system-x86_64: vhost_vdpa_listener_region_add received unaligned region qemu-system-x86_64: vhost_vdpa_listener_region_del received unaligned region
This error can be confusing for the user whereas we only need to skip the region (as it's already done after the error_report())
Rather than introducing a special case for TPM CRB memory section to not display the message in this case, simply replace the error_report() by a trace function (with more information, like the memory region name).
