[SCSI] SCSI core: fix leakage of scsi_cmnd's

Browse source

From: 	Alan Stern <stern@rowland.harvard.edu>

This patch (as559b) adds a new routine, scsi_unprep_request, which
gets called every place a request is requeued.  (That includes
scsi_queue_insert as well as scsi_requeue_command.)  It also changes
scsi_kill_requests to make it call __scsi_done with result equal to
DID_NO_CONNECT << 16.  (I'm not sure if it's necessary to call
scsi_init_cmd_errh here; maybe you can check on that.)  Finally, the
patch changes the return value from scsi_end_request, to avoid
returning a stale pointer in the case where the request was requeued.
Fortunately the return value is used in only place, and the change
actually simplified it.
