5.15-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 306ed1728e8438caed30332e1ab46b28c25fe3d8 ]
- There is no NFPROTO_IPV6 family for mark and NFLOG. - TRACE is also missing module autoload with NFPROTO_IPV6.
This results in ip6tables failing to restore a ruleset. This issue has been reported by several users providing incomplete patches.
Very similar to Ilya Katsnelson's patch including a missing chunk in the TRACE extension.
