scsi: libiscsi: qedi: convert iscsi_task.refcount from atomic_t to refcount_t

refcount_t type and corresponding API should be used instead of atomic_t
when the variable is used as a reference counter. This allows to avoid
accidental refcounter overflows that might lead to use-after-free
situations.

qed*: Utilize Firmware 8.15.3.0

This patch advances the qed* drivers into using the newer firmware -
This solves several firmware bugs, mostly related [but not limited to]
various init/deinit issues in various offloaded protocols.

It also introduces a major 4-Cached SGE change in firmware, which can be
seen in the storage drivers' changes.

In addition, this firmware is required for supporting the new QL41xxx
series of adapters; While this patch doesn't add the actual support,
the firmware contains the necessary initialization & firmware logic to
operate such adapters [actual support would be added later on].

scsi: qedi: fix build error without DEBUG_FS

scsi: qedi: fix build error without DEBUG_FS

Without CONFIG_DEBUG_FS, we run into a link error:

drivers/scsi/qedi/qedi_iscsi.o: In function `qedi_ep_poll':
qedi_iscsi.c:(.text.qedi_ep_poll+0x134): undefined reference to `do_not_recover'

qedi_fw.c:(.text.qedi_tmf_work+0x3b4): undefined reference to `do_not_recover'

This defines the symbol as a constant in this case, as there is no way to
set it to anything other than zero without DEBUG_FS. In addition, I'm renaming
it to qedi_do_not_recover in order to put it into a driver specific namespace,
as "do_not_recover" is a really bad name for a kernel-wide global identifier
when it is used only in one driver.

scsi: remove eh_timed_out methods in the transport template

Instead define the timeout behavior purely based on the host_template
eh_timed_out method and wire up the existing transport implementations
in the host templates. This also clears up the confusion that the
transport template method overrides the host template one, so some
drivers have to re-override the transport template one.

scsi: qedi: Add QLogic FastLinQ offload iSCSI driver framework.

The QLogic FastLinQ Driver for iSCSI (qedi) is the iSCSI specific module
for 41000 Series Converged Network Adapters by QLogic.

This patch consists of following changes:

- MAINTAINERS Makefile and Kconfig changes for qedi,
- PCI driver registration,
- iSCSI host level initialization,
- Debugfs and log level infrastructure.

The following indiviual changes are merged into this commit:

qedi: Add LL2 iSCSI interface for offload iSCSI.
qedi: Add support for iSCSI session management.
qedi: Add support for data path.
