Subject: [PATCH 13/21] netfilter: cttimeout: Make NF_CT_NETLINK_TIMEOUT depend on NF_CONNTRACK_TIMEOUT

From: Harsha Sharma <harshasharmaiitr@...il.com>

With this, remove ifdef for CONFIG_NF_CONNTRACK_TIMEOUT in
nfnetlink_cttimeout. This is also required for moving ctnl_untimeout
from nfnetlink_cttimeout to nf_conntrack_timeout.
