    batman-adv: fix local TT check for outgoing arp requests in DAT
    
    Change introduced by 88e48d7b3340ef07b108eb8a8b3813dd093cc7f7
    ("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 be1db4f6615b5e6156c807ea8985171c215c2d57
    ("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.
