When edk2 driver call EFI_MM_COMMUNICATION_PROTOCOL.Communicate,
the status of mm event can't return exactly to edk2 driver.

Ming:
  Current definition of EFI_MM_ENTRY_POINT follows PI spec 1.7 A (the latest
one). So, this is not a issue. 

  If you think there is the issue in PI spec, please join UEFI.org and
propose the change to PI spec first. 

Thanks
Liming
