[PATCH 02/14] do_for_each_ref_helper(): mark unused repository parameter

From: Jeff King <peff@peff.net>

Message-ID: <20230703064402.GB3537614@coredump.intra.peff.net>
In-Reply-To: <20230703064347.GA3524892@coredump.intra.peff.net>

This function gets a repository parameter because it's a callback for do_for_each_repo_ref_iterator(). But it's just a wrapper that passes along each call to a regular each_ref_fn callback, and the latter doesn't accept a repository argument.

Probably in the long run all of the each_ref_fn callbacks should get a repository parameter, too. But changing that now would require updates all over the code base. Until that happens, let's annotate this wrapper callback to quiet the compiler's -Wunused-parameter warning.
