[PATCH 13/50] netfilter: conntrack: remove unused init_net hook

[Pablo Neira Ayuso]

From: Florian Westphal <f...@strlen.de>

since adf0516845bcd0 ("netfilter: remove ip_conntrack* sysctl compat code")
the only user (ipv4 tracker) sets this to an empty stub function.

After this change nf_ct_l3proto_pernet_register() is also empty,
but this will change in a followup patch to add conditional register
of the hooks.
