blk-mq: fix stale tag depth for shared sched tags in blk_mq_update_nr_requests()
Commit 7f2799c546db ("blk-mq: cleanup shared tags case in
blk_mq_update_nr_requests()") moves blk_mq_tag_update_sched_shared_tags()
before q->nr_requests is updated, however, it's still using the old
q->nr_requests to resize tag depth.
Fix this problem by passing in expected new tag depth.
