Hello,

After commit "ipvs: Fix use-after-free in ip_vs_in" we planned
to call nf_register_net_hooks() only when rule is created but this
is net-next material and we should not leave leak in the error path.
I'll post a patch that adds .init handler for ipvs_core_dev_ops, so
that nf_register_net_hooks() is called there.
