This patch adds 'netns' module param to enable this new feature
(disabled by default), because it changes vsock's behavior with
network namespaces and could break existing applications.

Sorry, no.

I wonder if you can even design a legitimate, reasonable, use case
where these netns changes could break things.

I am totally against adding a module parameter for this, it's
incredibly confusing for users and will create a test scenerio
that is strongly less likely to be covered.
