[PATCH v9 2/4] scsi: Add PM_EVENT_POWEROFF into suspend callbacks

["Mario Limonciello (AMD)" <superm1@kernel.org>]

If the PM core uses hibernation callbacks for powering off the
system, drivers will receive PM_EVENT_POWEROFF and should handle
it the same as they previously handled PM_EVENT_HIBERNATE.

Support this case in the scsi driver.  No functional changes.
