Hi Ingo, Thomas,
this one-liner fixes a bug in balance_rt_tasks() which sometimes
manifests by having a lower prio task being scheduled while a higher
prio task is sitting waiting on another runqueue.
This is pretty hard to reproduce on low cpu count machines, for
example, I had to have sched_football run in a loop for ~38h before it
failed on a dual HT Xeon box.
