[CPUFREQ] Resolve time unit thinko in ondemand/conservative govs

ondemand and conservative governors are messing up time units in the
code path where NO_HZ is not enabled and ignore_nice is set. The walltime
idletime stored is in jiffies and nice time calculation is happening in
microseconds.

The problem was reported and diagnosed by Alexander here.

The patch below fixes this thinko.
