We found this bug actually through a code review by random. Since
(un)fortunately the queue pages were layouted in order, we've not
seen it earlier. It's certainly a bug and can cause kernel panic
if above observation is not met, probably in stress situation
of system. That means the "former" code accesses next page that
it has not allocated.
