Antonio Quartulli d2b6cc8e46 batman-adv: fix skb->data assignment 
skb_linearize(skb) possibly rearranges the skb internal data and then changes
the skb->data pointer value. For this reason any other pointer in the code that
was assigned skb->data before invoking skb_linearise(skb) must be re-assigned.

In the current tt_query message handling code this is not done and therefore, in
case of skb linearization, the pointer used to handle the packet header ends up
in pointing to poisoned memory. The packet is then dropped but the
translation-table mechanism is corrupted.
