Subject: [PATCH] x86, apic: Do not increment disabled_cpus from generic_processor_info.

 disabled_cpus has been incremented from the call path of
generic_processor_info (i.e from  acpi_register_lapic and
MP_processor_info) when a perticular cpu is not enabled. So, we can
remove the redundant increment of disabled_cpus from
generic_processor_info.
