blk-mq: remove useless checkings in blk_mq_update_nr_requests()

Browse source

[ Upstream commit 8bd7195fea ]

1) queue_requests_store() is the only caller of
blk_mq_update_nr_requests(), where queue is already freezed, no need to
check mq_freeze_depth;
2) q->tag_set must be set for request based device, and queue_is_mq() is
already checked in blk_mq_queue_attr_visible(), no need to check
q->tag_set.
