tools/power turbostat: reduce debug output

mainline inclusion
from mainline-v5.0-rc1
commit 0ec712e3
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I47H3V


CVE: NA

--------------------------------

A recent turbostat release increased topo.max_cpu_num
to make it convenient to handle sysfs bitmaps of 32-cpus.

But users, who regularly make use of "--debug", then saw a bunch of output
for cpus that were not present.

Remove that extra output by checking a cpu is online before dumping its info.
