batman-adv: Modify neigh_list only with rcu-list functions
The batadv_hard_iface::neigh_list is accessed via rcu based primitives.
Thus all operations done on it have to fulfill the requirements by RCU. So
using non-RCU mechanisms like hlist_add_head is not allowed because it
misses the barriers required to protect concurrent readers when accessing
the data behind the pointer.
Fixes: cef63419f7db ("batman-adv: add list of unique single hop neighbors per hard-interface")
