netfilter: nf_conntrack: add nf_ct_kfree_compat_sysctl_table
This patch is a cleanup. It adds nf_ct_kfree_compat_sysctl_table to release l4proto's compat sysctl table and set the compat sysctl table point to NULL. This new function will be used by follow-up patches. Signed-off-by: Gao feng <gaofeng@cn.fujitsu.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
