netfilter: ctnetlink: revert to dumping mark regardless of event type

[ Upstream commit 18fd4dc5223e260f9fad291750ffe4918b703ea0 ]

It seems that change was unintentional, we have userspace code that
needs the mark while listening for events like REPLY, DESTROY, etc.
Also include 0-marks in requested dumps, as they were before that fix.
