[CPUFREQ] speedstep-ich: fix error caused by 394122ab

"[CPUFREQ] cpumask: avoid playing with cpus_allowed in speedstep-ich.c"
changed the code to mistakenly pass the current cpu as the "processor"
argument of speedstep_get_frequency(), whereas it should be the type of
the processor.


Based on a patch by Dave Mueller.
