Zeng, Star 6c5801be6e UefiCpuPkg RegisterCpuFeaturesLib: NumberOfCpus may be uninitialized
NumberOfCpus local variable in GetAcpiCpuData will be uninitialized
when CpuS3DataDxe runs before DxeRegisterCpuFeaturesLib (linked by
CpuFeaturesDxe) because there is no code to initialize it at
(AcpiCpuData != NULL) execution path.

The issue is exposed after cefad282fb
and 38ee7bafa7.
There was negligence in that code review.
One further topic may be "Could EDK2 CI be enhanced to catch this kind
of uninitialized local variable case?". :)

This patch fixes this regression issue.
