ACPI: remove superfluous NULL pointer check from acpi_processor_get_throttling_info()
Dan's list contains:
drivers/acpi/processor_throttling.c +1139 acpi_processor_get_throttling_info(11) warning: variable derefenced before check 'pr'
acpi_processor_get_throttling_info() is never called with pr == NULL.
[ bart: the potential NULL pointer dereference was finally fixed in
(much later than mine) commit 5cfa245 but my patch is still valid ]
