batman-adv: Make bat_priv->primary_if an rcu protected pointer
The rcu protected macros rcu_dereference() and rcu_assign_pointer() for the bat_priv->primary_if need to be used, as well as spin/rcu locking. Otherwise we might end up using a primary_if pointer pointing to already freed memory. Signed-off-by: Marek Lindner <lindner_marek@yahoo.de> Signed-off-by: Sven Eckelmann <sven@narfation.org>
