test/scheduler: Wait for a bit for the governor to change the freq 

Issues like https://github.com/spdk/spdk/issues/1784

 showed that
governor may need some more time to properly adjust cpufreq's sysfs
knobs. In case we see that frequency setting hasn't changed after
given iteration, wait for 0.5s to make sure it finally settles.
