driver: macvlan: Remove the rcu member of macvlan_port
When free macvlan_port in macvlan_port_destroy, it is safe to free directly because netdev_rx_handler_unregister could enforce one grace period. So it is unnecessary to use kfree_rcu for macvlan_port. Signed-off-by: Gao Feng <fgao@ikuai8.com> Signed-off-by: David S. Miller <davem@davemloft.net>
