None of the callers of rename_ref() and copy_ref() care about errno, and as seen in the context here we already emit our own non-errno using error() in the case where we'd use it. So let's have it explicitly ignore errno, and do the same in commit_ref_update(), which is only used within other code in files_copy_or_rename_ref() itself which doesn't care about errno either. It might actually be sensible to have the callers use errno if the failure was filesystem-specific, and with the upcoming reftable backend we don't want to rely on that sort of thing, so let's keep ignoring that for now.
