[v2,2/2] batman-adv: Fix imbalanced locking in gw_node_update
Commit Message
8ffdea813e32cee3c60be36fb9e6a5e077e51ea0 used rcu_read_unlock without
using rcu_read_lock when gw_get_selected_gw_node didn't return a valid
gw_node.

Maybe the other patch is useful in the future... but changing the goto
to a return is less invasive and easier to understand
