hw/virtio: Add a protection against duplicate vu_scmi_stop calls

The QEMU CI fails in virtio-scmi test occasionally. As reported by
Thomas Huth, this happens most likely when the system is loaded and it
fails with the following error:

qemu-system-aarch64: ../../devel/qemu/hw/pci/msix.c:659:
msix_unset_vector_notifiers: Assertion `dev->msix_vector_use_notifier && dev->msix_vector_release_notifier' failed.
../../devel/qemu/tests/qtest/libqtest.c:200: kill_qemu() detected QEMU death from signal 6 (Aborted) (core dumped)

As discovered by Fabiano Rosas, the cause is a duplicate invocation of
msix_unset_vector_notifiers via duplicate vu_scmi_stop calls:

msix_unset_vector_notifiers
virtio_pci_set_guest_notifiers
vu_scmi_stop
vu_scmi_disconnect
...
qemu_chr_write_buffer

msix_unset_vector_notifiers
virtio_pci_set_guest_notifiers
vu_scmi_stop
vu_scmi_set_status
...
qemu_cleanup

While vu_scmi_stop calls are protected by vhost_dev_is_started()
check, it's apparently not enough. vhost-user-blk and vhost-user-gpio
use an extra protection, see f5b22d06fb (vhost: recheck dev state in
the vhost_migration_log routine) for the motivation. Let's use the
same in vhost-user-scmi, which fixes the failure above.
