3.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Simon Wunderlich <s...@simonwunderlich.de>
[ Upstream commit b2262df7fcf2c395eca564df83238e931d88d7bf ]
Since batadv_orig_node_new() sets the refcount to two, assuming that
the calling function will use a reference for putting the orig_node into
a hash or similar, both references must be freed if initialization of
the orig_node fails. Otherwise that object may be leaked in that error
case.
