    batman-adv: fix potential orig_node reference leak
    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
