netfilter: cttimeout: put back l4proto when replacing timeout policy
We forget to call nf_ct_l4proto_put when replacing the existing timeout policy. Acctually, there's no need to get ct l4proto before doing replace, so we can move it to a later position. Signed-off-by: Liping Zhang <liping.zhang@spreadtrum.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
