[01/10] batman-adv: move hardif refcount inc to batadv_neigh_node_new()
Commit Message
From: Marek Lindner <mareklindner@neomailbox.ch>
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.
