Subject: [PATCH 20/30] ACPI-processor: Fix jump targets in
 acpi_processor_get_throttling_info()

1. Adjust jump targets according to the current Linux coding
   style convention.

2. Delete a duplicate check then at the end.

3. Omit the explicit initialisation for the local variable "result"
   at the beginning which became unnecessary with this refactoring.
