batman-adv: Don't handle address updates when bla is disabled

Browse Source 
The bridge loop avoidance has a hook to handle address updates of the
originator. These should not be handled when bridge loop avoidance is
disabled - it might send some bridge loop avoidance packets which should
not appear if bla is disabled.
