ACPI: CPPC: Limit perf ctrs in PCC check only to online CPUs

per_cpu(cpc_desc_ptr, cpu) object is initialized for only the online
CPU via acpi_soft_cpu_online() --> __acpi_processor_start() -->
acpi_cppc_processor_probe().

However the function cppc_perf_ctrs_in_pcc() checks if the CPPC
perf-ctrs are in a PCC region for all the present CPUs, which breaks
when the kernel is booted with "nosmt=force".

Hence, limit the check only to the online CPUs.
