dm rq: take request_queue lock while clearing QUEUE_FLAG_STOPPED
Every call of queue_flag_clear_unlocked() after block device
initialization has finished is wrong if blk_cleanup_queue() can be
called concurrently. Convert queue_flag_clear_unlocked() into
queue_flag_clear() and protect it by the block layer queue lock.
Also, factor out dm_mq_start_queue().
