dm mpath: disable blk_abort_queue

commit 09c9d4c9b6a2b5909ae3c6265e4cd3820b636863 upstream.

Revert commit 224cb3e981f1b2f9f93dbd49eaef505d17d894c2
  dm: Call blk_abort_queue on failed paths

Multipath began to use blk_abort_queue() to allow for
lower latency path deactivation.  This was found to
cause list corruption:

   the cmd gets blk_abort_queued/timedout run on it and the scsi eh
   somehow is able to complete and run scsi_queue_insert while
   scsi_request_fn is still trying to process the request.
