batman-adv: move neigh_node list add into batadv_neigh_node_new()

Browse Source 
All batadv_neigh_node_* functions expect the neigh_node list item to be part
of the orig_node->neigh_list, therefore the constructor of said list item
should be adding the newly created neigh_node to the respective list.
