batman-adv: only drop packets of known wifi clients

bug introduced with 59b699cdee039d75915c354da06937102d1f9a84

If the source or destination mac address of an ethernet packet could not be found in the translation table the packet was dropped if AP isolation was turned on. This behavior would make it impossible to send broadcast packets over the mesh as the broadcast address will never enter the translation table.
