batman-adv: fix global protection fault during soft_iface destruction
batadv_mesh_free() schedules some RCU callbacks which need the bat_priv struct
to do their jobs, while free_netdev(), which is called immediately after, is
destroying the private data.
Put an rcu_barrier() in the middle so that free_netdev() is invoked only after
all the callbacks returned.
This bug has been introduced by ab8f433dd39be94e8617cff2dfe9f7eca162eb15
