batman-adv: use neigh_node's orig_node only as id

Browse source

The orig_node member of struct batadv_neigh_node is no longer used in
B.A.T.M.A.N. IV. But batadv_neigh_node_create() is still storing it.
Only batadv_v_ogm_route_update() uses it to check if we route toward
it - not needing the data stored in the batadv_orig_node object itself,
but merely a pointer to identify the originator.

The field cannot hold a proper reference because that would create a
reference cycle, so it must never be dereferenced. Rename it to
orig_node_id and mark it __private to make any future attempt to
dereference it immediately noticeable.
