UefiCpuPkg/CpuCommonFeaturesLib: Correct the CPU location check

Browse Source 
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3424

Processor location information check needs to updated
When Core 0 is disabled.

In C1e.c, change MSR_FEATURE_CONFIG to MSR_NEHALEM_POWER_CTL in comments
to match the correct MSR name.
