duntan 2a5c08caaf UefiCpuPkg: set EXTENDED_PROCESSOR_INFORMATION to 0
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.
