xfrm interface: fix list corruption for x-netns
commit c5d1030f23002430c2a336b2b629b9d6f72b3564 upstream.
dev_net(dev) is the netns of the device and xi->net is the link netns,
where the device has been linked.
changelink() must operate in the link netns to avoid a corruption of
the xfrm lists.
Note that xi->net and dev_net(xi->physdev) are always the same.
Before the patch, the xfrmi lists may be corrupted and can later trigger a
kernel panic.
Fixes: f203b76d7809 ("xfrm: Add virtual xfrm interfaces")
