UPSTREAM: netfilter: xtables: fix typo causing some targets not to load on IPv6

[ Upstream commit 306ed172 ]

- 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.
