[PATCH v8 03/16] ACPI: processor: Drop duplicated check on _STA (enabled + present)

[Jonathan Cameron]

The ACPI bus scan will only result in acpi_processor_add() being called
if _STA has already been checked and the result is that the
processor is enabled and present.  Hence drop this additional check.
