ip_tunnel: use exit_batch_rtnl() method
exit_batch_rtnl() is called while RTNL is held,
and devices to be unregistered can be queued in the dev_kill_list.
This saves one rtnl_lock()/rtnl_unlock() pair
and one unregister_netdevice_many() call.
This patch takes care of ipip, ip_vti, and ip_gre tunnels.
