dm-rq won't stop queue, meantime blk-mq won't stop one queue too, so
remove the check.
dm_stop_queue() actually tries to quiesce hw queues via blk_mq_quiesce_queue(),
we can't check via blk_queue_quiesced for avoiding unnecessary queue
quiesce because the flag is set before synchronize_rcu() and dm_stop_queue
may be called when synchronize_rcu from another blk_mq_quiesce_queue is
in-progress.
