rt2x00: Remove usage of deprecated radio_enabled & IEEE80211_CONF_CHANGE_RADIO_ENABLED

In the config() callback function the fields radio_enabled and
the change flag IEEE80211_CONF_CHANGE_RADIO_ENABLED have been
deprecated. This removes the usage of those fields by improving
antenna change detection in the antenna configuration function.
