rtnl: allow reply nla payloads to be smaller than headsize

Some netlink replies contain attributes with embeded payloads whose
length depends on the kernel version, e.g. IFLA_INET_CONF and
IFLA_INET6_CONF.

Deal with such cases by allowing the payloads to be shorter than
the expected size and by skipping struct members which would lead
to out-of-bounds accesses.
