WIP: zink: conditional-rendering restart
Here's something I noticed while debugging a conditional rendering failure. When we switch batches, we need to suspend and resume render-conditions as well as the queries, which we didn't do.
This didn't fix the issue I was working at, I found another fix to that which was unrelated to this MR.
Marked as WIP as I haven't done a full piglit test, so I don't know if this fixes any test-cases or not yet. I'll do that soon.
