compat: Backport nf_ct_netns_{get, put}()
This patch backports nf_ct_netns_get/put() in order to support a feature
in the follow up patch.
nf_ct_netns_{get,put} were first introduced in upstream net-next commit
ecb2421b5ddf ("netfilter: add and use nf_ct_netns_get/put") in kernel
v4.10, and then updated in commmit 7e35ec0e8044 ("netfilter: conntrack:
move nf_ct_netns_{get,put}() to core") in kernel v4.15. We need to
invoke nf_ct_netns_get/put() when the underlying nf_conntrack_l3proto
supports net_ns_{get,put}().
Therefore, there are 3 cases that we need to consider.
1) Before nf_ct_{get,put}() is introduced.
We just mock nf_ct_nets_{get,put}() and do nothing.
2) After 1) and before v4.15
Backports based on commit 7e35ec0e8044 .
3) Staring from v4.15
Use the upstream version.
