netfilter: nf_tables: NAT chain and extensions require NF_TABLES 



Move these options inside the scope of the 'if' NF_TABLES and
NF_TABLES_IPV6 dependencies. This patch fixes:

   net/ipv6/netfilter/nft_chain_nat_ipv6.o: In function `nft_nat_do_chain':
>> net/ipv6/netfilter/nft_chain_nat_ipv6.c:37: undefined reference to `nft_do_chain'
   net/ipv6/netfilter/nft_chain_nat_ipv6.o: In function `nft_chain_nat_ipv6_exit':
>> net/ipv6/netfilter/nft_chain_nat_ipv6.c:94: undefined reference to `nft_unregister_chain_type'
   net/ipv6/netfilter/nft_chain_nat_ipv6.o: In function `nft_chain_nat_ipv6_init':
>> net/ipv6/netfilter/nft_chain_nat_ipv6.c:87: undefined reference to `nft_register_chain_type'

that happens with:

CONFIG_NF_TABLES=m
CONFIG_NFT_CHAIN_NAT_IPV6=y
