netfilter: netns nf_conntrack: final netns tweaks
Add init_net checks to not remove kmem_caches twice and so on.
Refactor functions to split code which should be executed only for
init_net into one place.
ip_ct_attach and ip_ct_destroy assignments remain separate, because
they're separate stages in setup and teardown.
NOTE: NOTRACK code is in for-every-net part. It will be made per-netns
after we decidce how to do it correctly.
