[PATCH 1/2] Fix radio remove works

[Otcheretianski, Andrei]

Hi,
Checking work->wpa_s doesn't make sense, since it is set in radio_add_work and never unset.
Anyway I think the fix should be more like this:

@@ -3259,6 +3259,7 @@ static void radio_remove_interface(struct wpa_supplicant *wpa_s)
                   wpa_s->ifname, radio->name);
        dl_list_del(&wpa_s->radio_list);
        if (!dl_list_empty(&radio->ifaces)) {
+               radio_remove_works(wpa_s, NULL, 0);
                wpa_s->radio = NULL;
                return; /* Interfaces remain for this radio */
        }

Regards,
Andrei
