This should fix #31754 and follow-up #25343. Before the latter, the closure was visited twice in the context of the enclosing fn, which made even a single closure with a loop label emit a warning. With this change, the closure is still visited within the context of the main fn (which is intended, since it is not a separate item) but resets the found loop labels while being visited. Fixes: #31754
