netfilter: decouple nf_hook_entry and nf_hook_ops
During nfhook traversal we only need a very small subset of
nf_hook_ops members.
We need:
- next element
- hook function to call
- hook function priv argument
Bridge netfilter also needs 'thresh'; can be obtained via ->orig_ops.
nf_hook_entry struct is now 32 bytes on x86_64.
A followup patch will turn the run-time list into an array that only
stores hook functions plus their priv arguments, eliminating the ->next
element.
