  Seems to me we used to expect type would be used to keep the trace
of the type of the vif, but we never use that variable, only for that
test. I would just kill it from that block

    list = virConfGetValue(conf, "vif");
    if (list && list->type == VIR_CONF_LIST) {
        list = list->list;
        while (list) {
            int type = -1;

  since we never use the value anywhere !
