Subject: kABI: protect struct nf_conn
Patch-mainline: never, kabi
References: kabi

In netfilter-stable-17_11_16, commit
e1bf1687740ce1a3598a1c5e452b852ff2190682 (netfilter: nat: Revert
"netfilter: nat: convert nat bysrc hash to rhashtable") changed one
member type from struct rhlist_head to struct hlist_node.  It made the
kABI checker complaining.

Given the both types contain 2 pointers, just hide the change from the
kABI checker as this is only a nat core member.
