Subject: [PATCH 3.14 122/140] batman-adv: always run purge_orig_neighbors

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

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

[ Upstream commit 7b955a9fc164487d7c51acb9787f6d1b01b35ef6 ]

The current code will not execute batadv_purge_orig_neighbors() when an
orig_ifinfo has already been purged. However we need to run it in any
case. Fix that.

This is a regression introduced by
7351a4822d42827ba0110677c0cbad88a3d52585
("batman-adv: split out router from orig_node")
