I think we can update NFT_REJECT_INET so it depends on NFT_REJECT_IPV4
and NFT_REJECT_IPV6. This doesn't allow here CONFIG_NFT_REJECT_INET=y
and CONFIG_NF_REJECT_IPV6=m.

I mean, just like we do with NFT_FIB_INET.

BTW, I think this problem has been is not related to the recent patch,
but something older that kbuild robot has triggered more easily for
some reason?

Thanks for your patch!
