In in6_update_ifa(), jump to 'cleanup' rather than returning directly

in one additional case, avoiding an ifaddr reference leak.

Defer releasing the in6_ifaddr's in6_ifaddrhead reference until the
end of in6_unlink_ifa(), as callers are inconsistent regarding whether
or not they hold a reference across the call.  This avoids using the
ifaddr after it may have been freed.
