inet netfilter: Remove hook from ip6t_do_table, arp_do_table, ipt_do_table
The values of ops->hooknum and state->hook are guaraneted to be equal
making the hook argument to ip6t_do_table, arp_do_table, and
ipt_do_table is unnecessary. Remove the unnecessary hook argument.
In the callers use state->hook instead of ops->hooknum for clarity and
to reduce the number of cachelines the callers touch.
