A previous commit for the multi interface optimization did not change the member access for neigh_node to their respective new ifinfo structures for the network coding implementation.

This was introduced by change 9bb33b8d88e318c4879d37d06ad28e3e018b9036 ("batman-adv: split tq information in neigh_node struct")
