According to PI errata 0000654 and 000811, we need use 0xFFFE to instead of 0 for EFI_SMBIOS_PROTOCOL.Add() SmbiosHandle parameter to assign a unique handle to the SMBIOS record, and for EFI_SMBIOS_PROTOCOL.GetNext() SmbiosHandle parameter to get the first matched SMBIOS handle or indicate no more SMBIOS record.
