block: blk-mq: make blk_sync_queue support mq
This patch moves synchronization on mq->delay_work from blk_mq_free_queue() to blk_sync_queue(), so that blk_sync_queue can work on mq. Cc: Jens Axboe <axboe@kernel.dk> Signed-off-by: Ming Lei <tom.leiming@gmail.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
