net: ip6_vti: require CAP_NET_ADMIN in the device netns for changelink

In the Linux kernel, the following vulnerability has been resolved:

net: ip6_vti: require CAP_NET_ADMIN in the device netns for changelink

vti6_changelink() operates on at most two netns, dev_net(dev) and the
tunnel link netns t->net. They differ once the device is created in or
moved to a netns other than the one the request runs in. The rtnl
changelink path checks CAP_NET_ADMIN only against dev_net(dev), so a
caller privileged there but not in t->net can rewrite a tunnel that
lives in t->net.

Gate vti6_changelink() on rtnl_dev_link_net_capable() at its top,
before any attribute is parsed.
