[PATCH 1/3] skip property update actions when wpa_config_set returns 1

[Matthew Wang]

When network properties are updated via dbus, wpa_config_set is used to
update the property in the wpa_ssid struct. If it returns 1, the
property was not changed and there's no need to perform any of the
update actions.
