[PATCH net-next v2 1/1] driver: ipvlan: Free ipvl_port directly with kfree instead of kfree_rcu

[fgao]

From: Gao Feng <gfree.w...@gmail.com>

There is no one which may reference the ipvlan port when free it in
ipvlan_port_create and ipvlan_port_destroy. So it is unnecessary to
use kfree_rcu.

 v2: Remove the rcu of ipvl_port directly
 v1: Initial version
