Kuniyuki Iwashima 954a2b4071 rtnetlink: Try the outer netns attribute in rtnl_get_peer_net(). ...

Xiao Liang reported that the cited commit changed netns handling
in newlink() of netkit, veth, and vxcan.

Before the patch, if we don't find a netns attribute in the peer
device attributes, we tried to find another netns attribute in
the outer netlink attributes by passing it to rtnl_link_get_net().

Let's restore the original behaviour.
