[PATCH 1/2] ACPI/Processor: Clear unuseful variable count in the acpi_processor_preregister_performance()

[Lan Tianyu <tianyu.lan@intel.com>]

The variable count in the acpi_processor_preregister_performance() is only initalized
as one for one cpu and increased by one when find another cpu that share same dependency
domain. Otherwise, it isn't referenced somewhere else.
