We don't encode argument types into function names and since besides
nft_do_chain() there are only AF-specific versions, there is no risk
of confusion.

Minor nf_chain_type cleanups:
- reorder struct to plug a hoe
- rename struct module member to "owner" for consistency
- rename nf_hookfn array to "hooks" for consistency
- reorder initializers for better readability

In some cases we neither take a reference to the AF info nor to the
chain type, allowing the module to be unloaded while in use.

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
