After blk_cleanup_queue() finished no new requests will be queued to a
SCSI LLD. However, that function doesn't wait for already queued
requests to finish. I have verified with ib_srp LLD that the
blk_abort_queue() call triggers the "SRP abort called" kernel log
message generated by ib_srp when srp_abort() is called.
