[B.A.T.M.A.N.] [PATCH 2/2] batman-adv: fix orig_node multiif regression in network coding

[Simon Wunderlich <sw@simonwunderlich.de>]

From: Simon Wunderlich <simon@open-mesh.com>

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

This was introduced by change de6bcc76ea84fecb136f8c8f5ba1862e4a13f06b
("batman-adv: split out router from orig_node")
