netfilter: ctnetlink: remove dead NAT code
The NAT range to nlattr conversation callbacks and helpers are entirely dead code and are also useless since there are no NAT ranges in conntrack context, they are only used for initially selecting a tuple. The final NAT information is contained in the selected tuples of the conntrack entry. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
