Subject: [PATCH v3 5/6] blk-mq-tag: fix functions documentation

From: Chengming Zhou <zhouchengming@...edance.com>

There are some stale functions documentation in blk-mq-tag, since
the prototype of busy_tag_iter_fn() has changed. Fix it as we're here.

Fixes: 2dd6532e9591 ("blk-mq: Drop 'reserved' arg of busy_tag_iter_fn")
