Since the introduction of 'BT_TAG_ITER_STARTED' by commit 602380d28e28
("blk-mq: add blk_mq_all_tag_iter"), the bt_tags_for_each() is not only
used for started request, e.g., in below case:
blk_mq_hctx_has_requests()
-> blk_mq_all_tag_iter()
-> __blk_mq_all_tag_iter() --> only BT_TAG_ITER_STATIC_RQS is set
-> bt_tags_for_each()
-> bt_tags_iter()
