dm: fix a couple locking issues with use of block interfaces old_stop_queue() was checking blk_queue_stopped() without holding the q->queue_lock. dm_requeue_original_request() needed to check blk_queue_stopped(), with q->queue_lock held, before calling blk_mq_kick_requeue_list(). And a side-effect of that change is start_queue() must also call blk_mq_kick_requeue_list(). Signed-off-by: Mike Snitzer <snitzer@redhat.com>
