tools/kvm_stat: fix crash when filtering out all non-child trace events When we apply a filter that will only leave child trace events, we receive a ZeroDivisionError when calculating the percentages. In that case, provide percentages based on child events only. To reproduce, run 'kvm_stat -f .*[\(].*'.
