This would be a spec violation - once no active QPs are attached,
the consumer should be able to assume he will get no new events.

But I agree we can regard this as a separate issue, since it does not
affect IPoIB/CM.

So for now I'm going for your proposed change: merge all QP associated events
and the CMD IFC events to a single EQ.
