Change introduced by d6bd8b36fa1f3d72a6fd5942a6e9bde6ddafcd0d ("batman-adv: make DAT drop ARP requests targeting local clients") implements a check that prevents DAT from using the caching mechanism when the client that is supposed to provide a reply to an arp request is local.
However change brought by 3e26722bc9f248ec4316749fc1957365c0fa5e4b ("batman-adv: make the Distributed ARP Table vlan aware") has not converted the above check into its vlan aware version thus making it useless when the local client is behind a vlan.
Fix the behaviour by properly specifying the vlan when checking for a client being local or not.
