netfilter: fix CONFIG_NF_REJECT_IPV6=m link error
We get a new link error with CONFIG_NFT_REJECT_INET=y and CONFIG_NF_REJECT_IPV6=m
after larger parts of the nftables modules are linked together:
net/netfilter/nft_reject_inet.o: In function `nft_reject_inet_eval':
nft_reject_inet.c:(.text+0x17c): undefined reference to `nf_send_unreach6'
nft_reject_inet.c:(.text+0x190): undefined reference to `nf_send_reset6'
The problem is that with NF_TABLES_INET set, we implicitly try to use
the ipv6 version as well for NFT_REJECT, but when CONFIG_IPV6 is set to
a loadable module, it's impossible to reach that.
The best workaround I found is to express the above as a Kconfig
dependency, forcing NFT_REJECT itself to be 'm' in that particular
configuration.
