Sven Eckelmann fa88c65601 batman-adv: dat: prevent false sharing between VLANs 
commit 20d7658b74 upstream.

The local hash of DAT entries is supposed to be VLAN (VID) aware. But
the adding to the hash and the search in the hash were not checking the VID
information of the hash entries. The entries would therefore only be
correctly separated when batadv_hash_dat() didn't select the same buckets
for different VIDs.
