cpustates: Fix for error when trying to use cpustates with hotplugged cores

Browse Source 
It is not possible to read frequencies from a core that has been hotplugged.
The code will now set the current and max frequencies of hotplugged cores
to None.

This still doesn't work for devices that have dynamic hotplug enabled
