dm: Fix two race conditions related to stopping and starting queues Ensure that all ongoing dm_mq_queue_rq() and dm_mq_requeue_request() calls have stopped before setting the "queue stopped" flag. This allows to remove the "queue stopped" test from dm_mq_queue_rq() and dm_mq_requeue_request(). Use BLK_MQ_S_STOPPED instead of QUEUE_FLAG_STOPPED.
