Completion events are fine -- at worst the consumer gets a spurious
event but doesn't find any CQEs.  I see the point about async events.
It does make sense to merge the async event and command EQs to get
good ordering -- splitting them doesn't make much performance
difference I guess.

I don't want to put a fix in that we have to back out later.  Let's
figure out how to fix this properly in the first place.  But I think
just merging async events and command completions into one EQ suffices.
