refs API: make resolve_gitlink_ref() not set errno

I have carefully read the upstream callers of resolve_gitlink_ref() and determined that they don't care about errno. So let's move away from the errno-setting refs_resolve_ref_unsafe() wrapper to refs_werrres_ref_unsafe(), and explicitly ignore the errno it sets for us.
