Re: [RTNL]: Add missing link netlink attribute policy definitions

IFLA_LINK is no longer a write-only attribute on the kernel
side and must thus be validated. Same goes for the newly
introduced IFLA_LINKINFO.

Fixes undefined behaviour if either of the attributes are
not well formed.

Applied, thanks Thomas.
