netfilter: x_tables: move hook state into xt_action_param structure
Place pointer to hook state in xt_action_param structure instead of copying the fields that we need. After this change xt_action_param fits into one cacheline. This patch also adds a set of new wrapper functions to fetch relevant hook state structure fields. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
