module/cpufreq: Make use_governor() affect only online CPUs

Browse Source 
Turns out you can't change cpufreq attributes on an offlined
CPU (no big surprise!), so use_governor() will fail if a whole
frequency domain has been hotplugged out.

Change the default behaviour to only target online CPUs.
