That shoule not happen until my later patches which switch that all
over.
See patch 5/13 which I posted on Thursday, Jul 10. That's when the
transition from "global queue state + per-queue state" into "only
per-queue state" happens.
Until that point, we have to keep the existing quasi-multi-queue
semantics in order to not break drivers etc.
