This patch introduced a regression when determining the accuracy of the
policy with respect to allotting threads the expected runtime budget:

root@phytec-mira-evl:~# evl test sched-quota-accuracy
sched-quota-accuracy: 494.0%

The proper result would rather be close to the following:

root@phytec-mira-evl:~# evl test sched-quota-accuracy
sched-quota-accuracy: 99.1%
