Ming Lei 26ee94ba34 blk-mq: don't grab rq's refcount in blk_mq_check_expired() 
[ Upstream commit c797b40ccc340b8a66f7a7842aecc90bf749f087 ]

Inside blk_mq_queue_tag_busy_iter() we already grabbed request's
refcount before calling ->fn(), so needn't to grab it one more time
in blk_mq_check_expired().

Meantime remove extra request expire check in blk_mq_check_expired().
