credit: recalculate per-cpupool credits when updating timeslice

When modifying the timeslice of the credit scheduler in a cpupool the
cpupool global credit value (n_cpus * credits_per_tslice) isn't
recalculated. This will lead to wrong scheduling decisions later.

Do the recalculation when updating the timeslice.
