batman-adv: prevent duplication of ARP replies when DAT is used
If none of the backbone gateways in a bla setup has already knowledge of the mac address searched for in an incoming ARP request from the backbone an address resolution via the DHT of DAT is started. The gateway can send several ARP requests to different DHT nodes and therefore can get several replies. This patch assures that not all of the possible ARP replies are returned to the backbone by checking the local DAT cache of the gateway. If there is an entry in the local cache the gateway has already learned the requested address and there is no need to forward the additional reply to the backbone. Furthermore it is checked if this gateway has claimed the source of the ARP reply and only forwards it to the backbone if it has claimed the source or if there is no claim at all.
