Subject: [PATCH 4/5] acpi/processor: Fix the return value of acpi_processor_ids_walk()

ACPI driver should make sure all the processor IDs in their ACPI Namespace
are unique for CPU hotplug. the driver performs a depth-first walk of the
namespace tree and calls the acpi_processor_ids_walk().

But, the acpi_processor_ids_walk() will return true if one processor is
checked, that cause the walk break after walking pass the first processor.

Repace the value with AE_OK which is the standard acpi_status value.

Fixes 8c8cb30f49b8 ("acpi/processor: Implement DEVICE operator for processor enumeration")
