netfilter: netns nf_conntrack: add ->ct_net -- pointer from conntrack to netns
Conntrack (struct nf_conn) gets pointer to netns: ->ct_net -- netns in which
it was created. It comes from netdevice.
->ct_net is write-once field.
Every conntrack in system has ->ct_net initialized, no exceptions.
->ct_net doesn't pin netns: conntracks are recycled after timeouts and
pinning background traffic will prevent netns from even starting shutdown
sequence.
Right now every conntrack is created in init_net.
