x86, cpufreq: fix ondemand governor to take aperf/mperf feedback

APERF/MPERF MSRs provides feedback about actual freq in
eplased time, which could be different from requested freq by
governor. However currently ondemand governor only takes that
feedback at freq down path. We should do that for scale up too.
