    [libyelp/yelp-document.c] Don't keep trying to refree freed resources
    
    Request structs are freed with request_try_free. If the request can't be
    freed, it just adds itself in idle callback to try again. But it wasn't
    returning FALSE, so it could end up repeatedly trying to free, even when
    the struct was freed.
