ACPI: processor: Drop duplicate setting of shared_cpu_map

'shared_cpu_map', stored as part of the per-processor acpi_processor_performance structre, is used to store CPUs that share a performance domain. By definition it contains the owning CPU. While building the 'shared_cpu_map' it is being set twice - once while initialising the performance domains and again when matching CPUs belonging to the same domain. Drop the unnecessary initialisation. Signed-off-by: Punit Agrawal <[email protected]> Signed-off-by: Rafael J. Wysocki <[email protected]>
