remote.c: make singular free_ref() public

We provide a free_refs() function to free a list, but there's no easy way for a caller to free a single ref. Let's make our singular free_ref() function public. Since its name is so similar to the list-freeing free_refs(), and because both of those functions have the same signature, it might be easy to accidentally use the wrong one. Let's call the singular version the more verbose "free_one_ref()" to distinguish it. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
