MdeModulePkg/DxeCore: Please static checker for false report

After commit 57df17fe26, some static check reports suspicious NULL pointer
deference at line:

  Entry->MachineType = Entry->Emulator->MachineType;
                       ^^^^^^^^^^^^^^^

within function PeCoffEmuProtocolNotify().

However, 'Entry->Emulator' is guaranteed to have a non-NULL value when
previous call to the CoreHandleProtocol() returns EFI_SUCCESS.

This commit will re-write the return status check for CoreHandleProtocol()
to add explicit NULL pointer check for protocol instance pointer.
