[B.A.T.M.A.N.] [PATCH-maint 1/3] batman-adv: fix neigh_ifinfo imbalance

[Simon Wunderlich <sw@simonwunderlich.de>]

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

The neigh_ifinfo object must be freed if it has been used in
batadv_iv_ogm_process_per_outif().

This is a regression introduced by
9bb33b8d88e318c4879d37d06ad28e3e018b9036 ("batman-adv: split tq
information in neigh_node struct")
