8021q: Vlan driver should use rcu_barrier() on unload instead of syncronize_net()

The VLAN 8021q driver needs to call rcu_barrier() when unloading the module,
instead of syncronize_net().  This is needed to make sure that outstanding
call_rcu() callbacks have completed, before the callback function code is
removed on module unload.
