ACPI / processor: Fix the return value of acpi_processor_ids_walk()

[ Upstream commit d0381bf4f80c571dde1244fe5b85dc35e8b3f546 ]

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

But, the acpi_processor_ids_walk() mistakes the return value. If a
processor is checked, it returns true which causes the walk break
immediately, and other processors will never be checked.

Repace the value with AE_OK which is the standard acpi_status value.
And don't abort the namespace walk even on error.
