They are not always handled correctly. For monitor_started, it should be true when driver works in monitor mode, and should be false at other times. For monitor_vdev_id, it should be -1 when driver doesn't work in monitor mode. For monitor_vdev_created, it should be true after monitor vdev is created successfully and should be false at other times. For monitor_conf_enabled, it should be true when mac80211 sets IEEE80211_CONF_MONITOR, and should be false at other times. Handle those state variables according to above descriptions.
