ACPI: pdc init related memory leak with physical CPU hotplug
arch_acpi_processor_cleanup_pdc() in x86 and ia64 results in memory allocated for _PDC objects that is never freed and will cause memory leak in case of physical CPU remove and add. Patch fixes the memory leak by freeing the objects soon after _PDC is evaluated.
