batman-adv: move hardif refcount inc to batadv_neigh_node_new()

The batadv_neigh_node cleanup function 'batadv_neigh_node_free_rcu()' takes care of reducing the hardif refcounter, hence it's only logical to assume the creating function of that same object 'batadv_neigh_node_new()' takes care of increasing the same refcounter.
