[SCSI] SCSI core: fix leakage of scsi_cmnd's
Actually, just one problem and one cosmetic fix: 1) We need to dequeue for the loop and kill case (it seems easiest simply to dequeue in the scsi_kill_request() routine) 2) There's no real need to drop the queue lock. __scsi_done() is lock agnostic, so since there's no requirement, let's just leave it in to avoid any locking issues.
