Tweaked KToonservative two variables & fix

1- Variables for hotplugging
When policy-cur goes below down_freq_threshold_hotplug then the hotplug driver disables the extra core. Same thing for the other variable.

However I choose to use the gogo logic operator to determine whether or not it is needed to disable the core. I think using OR might yield better results, heh, depending on the hotplug_thresold put

2- Fixed during boost cycles : fixed the statement at line 568/713
