In ancient times, we used to disallow the same source ref to be
pushed to more than one places, e.g. "git push there master:master
master:naster" was disallowed. We later lifted this restriction
with db27ee63929f (send-pack: allow the same source to be pushed
more than once., 2005-08-06) and there no longer is anybody that
sets peer_ref for the source side of the ref list in the push
codepath since then.
Remove one leftover no-op in a loop that iterates over the source
side of ref list (i.e. our local ref) to see if it can/should be
sent to a matching destination ref while skipping ones that is
marked with peer_ref (which will never exist, so we do not skip
anything).

This looks good to me. I was curious how difficult it would be to verify
the "no longer is anybody that sets peer_ref" claim. It's actually quite
easy. All of the call-sites just feed the result of get_local_heads(),
which is easy to verify does not ever set peer_ref. Looking at the
current code, I think you could even drop the "src" parameter and just
have match_push_refs call get_local_heads() itself, though that does
feel like a step backwards in terms of function generality.
As an aside, I have always found the embedded "next" and "peer_ref"
pointers in "struct ref" to be hacky. They are not properties of the ref
at all, and the "refs to fetch" list would be more logically represented
as a list of pairs of refs (and then I would not have to ever remember
whether the peer is the local or remote ref in a given case). Probably
not worth worrying about at this point, though, as the code fallout
would be significant for little gain.
