ACPI: processor: Remove freq Qos request for all CPUs
The freq Qos request would be removed repeatedly if the cpufreq policy
relates to more than one CPU. Then, it would cause the "called for unknown
object" warning.
Remove the freq Qos request for each CPU relates to the cpufreq policy,
instead of removing repeatedly for the last CPU of it.
