netfilter: replace NF_NAT_NEEDED with IS_ENABLED(CONFIG_NF_NAT)
NF_NAT_NEEDED is true whenever nat support for either ipv4 or ipv6 is enabled. Now that the af-specific nat configuration switches have been removed, IS_ENABLED(CONFIG_NF_NAT) has the same effect. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
