Corrado Zoccolo 355b659c87 cfq-iosched: avoid probable slice overrun when idling ...

If the average think time is larger than the remaining time slice
for any given queue, don't allow it to idle. A succesful idle also
means that we need to dispatch and complete a request, so if we don't
even have time left for the idle process, we would overrun the slice
in any case.
