batman-adv: Trigger genl notification on sysfs config change
The generic netlink code is expected to trigger notification messages when configuration might have been changed. But the configuration of batman-adv is most of the time still done using sysfs. So the sysfs interface should also trigger the corresponding netlink messages via the "config" multicast group.
