[PATCH AUTOSEL 6.3 56/67] netfilter: conntrack: define variables exp_nat_nla_policy and any_addr with CONFIG_NF_NAT

[Sasha Levin <sashal@kernel.org>]

From: Tom Rix <trix@redhat.com>

[ Upstream commit 224a876e37543eee111bf9b6aa4935080e619335 ]

gcc with W=1 and ! CONFIG_NF_NAT
net/netfilter/nf_conntrack_netlink.c:3463:32: error:
  ‘exp_nat_nla_policy’ defined but not used [-Werror=unused-const-variable=]

      |                                ^~~~~~~~~~~~~~~~~~
net/netfilter/nf_conntrack_netlink.c:2979:33: error:
  ‘any_addr’ defined but not used [-Werror=unused-const-variable=]
 2979 | static const union nf_inet_addr any_addr;
      |                                 ^~~~~~~~

These variables use is controlled by CONFIG_NF_NAT, so should their definitions.
