Set EXTENDED_PROCESSOR_INFORMATION to 0 in API MpInitLibGetProcessorInfo() of MpInitLibUp. This commit use ZeroMem() to set all fileds in output EFI_PROCESSOR_INFORMATION to 0 before StatusFlag field is reassigned. Previously EXTENDED_PROCESSOR_INFORMATION in the API MpInitLibGetProcessorInfo() of MpInitLibUp is ignored. In PEI/DXE MpInitLib, EXTENDED_PROCESSOR_INFORMATION will be retrived when BIT24 of input ProcessorNumber is set. This commit can avoid garbage in the output structure in MpInitLibGetProcessorInfo() of MpInitLibUp.
