cpufreq: interactive: Re-evaluate immediately in load change callback

Previously, there was a limitation in load change callback that it
can't attempt to wake up a task. Therefore the best we can do is to
schedule timer at current jiffy. The timer function will only be
executed at next timer tick. This could take up to 10ms.

Now that this limitation is removed, re-evaluate load immediately upon
receiving this callback.
