When use the "make W=1Arch=x86_64 net/" command for compilation, the
following issue occurs:
net/netfilter/nf_nat_proto.c:56:6: warning: no previous prototype for
‘nf_nat_csum_recalc’ [-Wmissing-prototypes]
 void nf_nat_csum_recalc(struct sk_buff *skb,
      ^~~~~~~~~~~~~~~~~~
To fix the issue, add the necessary header files.
