Marek Lindner 44524fcdf6 batman-adv: Correct rcu refcounting for neigh_node 
It might be possible that 2 threads access the same data in the same
rcu grace period. The first thread calls call_rcu() to decrement the
refcount and free the data while the second thread increases the
refcount to use the data. To avoid this race condition all refcount
operations have to be atomic.
