I don't think it's needed, and anyway I don't see how it fixes
things. The problem only happens when the new CQ or QP has the same
number as an old CQ/QP, so the test of cq->cqn == cqn might still pass
even if the cq has changed (there's no guarantee the upper bits won't
repeat -- or someone could be using 24 bits for index)
