Subject: [PATCH] ipv6: addrconf: add missing validate_link_af handler

We still need a validate_link_af() handler with an appropriate nla policy,
similarly as we have in IPv4 case, otherwise size validations are not being
done properly in that case.

Fixes: f53adae4eae5 ("net: ipv6: add tokenized interface identifier support")
Fixes: bc91b0f07ada ("ipv6: addrconf: implement address generation modes")
