Bart Van Assche a45a1f3614 scsi: scsi-mq: Always unprepare before requeuing a request ...

One of the two scsi-mq functions that requeue a request unprepares a
request before requeueing (scsi_io_completion()) but the other function
not (__scsi_queue_insert()). Make sure that a request is unprepared
before requeuing it.

Fixes: commit d285203cf6 ("scsi: add support for a blk-mq based I/O path.")
