ACPI: processor: Fix memory leaks in error paths of processor_add()
[ Upstream commit 47ec9b417ed9b6b8ec2a941cd84d9de62adc358a ]
If acpi_processor_get_info() returned an error, pr and the associated
pr->throttling.shared_cpu_map were leaked.
The unwind code was in the wrong order wrt to setup, relying on
some unwind actions having no affect (clearing variables that were
never set etc). That makes it harder to reason about so reorder
and add appropriate labels to only undo what was actually set up
in the first place.
