netfilter: ip6tables: Split ip6t_unregister_table() into pre_exit and exit helpers.
The pre_exit will un-register the underlying hook and .exit will do
the table freeing. The netns core does an unconditional synchronize_rcu
after the pre_exit hooks insuring no packets are in flight that have
picked up the pointer before completing the un-register.
Fixes: b9e69e127397 ("netfilter: xtables: don't hook tables by default")
