This patch reduces code duplication. There are two functional changes in
this patch:

- It causes scsi_mq_prep_fn() to clear driver-private command data, just
  like the already upstream commit 1bad6c4a ("scsi: zero per-cmd
  private driver data for each MQ I/O").

- The initialization of .prot_sdb is moved from scsi_mq_prep_fn() into
  scsi_init_request().

If a device is blocked, make __scsi_remove_device() cause it to
transition to the DEL state. This means that all the commands issued in
.shutdown() will error in the mid-layer, thus making the removal proceed
without being stopped.

Bottomley. This patch avoids that the following lockup occurs:

Serializing SCSI device state changes avoids that two state changes can
occur concurrently, e.g. the state changes in scsi_target_block() and
__scsi_remove_device(). This serialization is essential to make patch
"Make __scsi_remove_device go straight from BLOCKED to DEL" work
reliably.

Enable this mechanism for all scsi_target_*block() callers but not for
the scsi_internal_device_unblock() calls from the mpt3sas driver because
that driver can call scsi_internal_device_unblock() from atomic context.

Dereferencing shost from scsi_exit_rq() is not safe because the SCSI
host may already have been freed when scsi_exit_rq() is called.
Increasing the shost reference count in scsi_init_rq() and dropping that
reference in scsi_exit_rq() is nontrivial since scsi_host_dev_release()
may sleep and since scsi_exit_rq() may be called from interrupt
context. Since scsi_exit_rq() only needs a single bit from shost, copy
that bit into struct scsi_cmnd.

We need to add a bus reset no-op as without it some of the LUNs attached to a
vport may go offline when the error handler escalates to host reset due to not
having a bus reset handler in the driver. What happens is we escalate to host
reset which does a soft link down/link up to reset the adapter. However with
multiple vports attached it's been observed that if the vports do log back into
the target within 5 seconds, the SCSI layer offlines the devices most likely
due to a TUR timing out to verify that the device is online. Adding a bus
reset handler will cause the TUR to be sent after the bus reset handler where
the devices will still be online if the bus reset is initiated by sg_reset
(which is the case in the test that was failing). The bus reset will succeed
and not needlessly bring the device offline/online.
