xfrm: remove the unnecessary .net_exit for xfrmi
The xfrm_if(s) on each netns can be deleted when its xfrmi dev is
deleted. xfrmi dev's removal can happen when:
a. netns is being removed and all xfrmi devs will be deleted.
b. rtnl_link_unregister(&xfrmi_link_ops) in xfrmi_fini() when
xfrm_interface.ko is being unloaded.
So there's no need to use xfrmi_exit_net() to clean any xfrm_if up.
v1->v2:
- Fix some changelog.
