mac80211: Fix wpa_supplicant config removal ubus call

If mac80211_setup_supplicant() is called with enabled=0 then it should just
destroy the interface and remove the configuration from wpa_supplicant. But
the ubus method call always returned

  Command failed: Method not found

because the actual name of the method is "config_remove".
