batman-adv: Make bat_priv->curr_gw an rcu protected pointer

Browse source

The rcu protected macros rcu_dereference() and rcu_assign_pointer()
for the bat_priv->curr_gw need to be used, as well as spin/rcu locking.

Otherwise we might end up using a curr_gw pointer pointing to already
freed memory.
