netfilter: nf_tables: make chain types override the default AF functions
Currently the AF-specific hook functions override the chain-type specific
hook functions. That doesn't make too much sense since the chain types
are a special case of the AF-specific hooks.
Make the AF-specific hook functions the default and make the optional
chain type hooks override them.
As a side effect, the necessary code restructuring reduces the code size,
f.i. in case of nf_tables_ipv4.o:
nf_tables_ipv4_init_net | -24
nft_do_chain_ipv4 | -113
2 functions changed, 137 bytes removed, diff: -137
