scsi: mpt3sas: Unblock device after controller reset
commit 7ff723ad0f87feba43dda45fdae71206063dd7d4 upstream.
While issuing any ATA passthrough command to firmware the driver will
block the device. But it will unblock the device only if the I/O
completes through the ISR path. If a controller reset occurs before
command completion the device will remain in blocked state.
Make sure we unblock the device following a controller reset if an ATA
passthrough command was queued.
