- The return value from ProcessModuleEntryPointList() is returned.
- If _gDriverUnloadImageCount is greater
- than zero, then an unload handler must be registered for this image and
- the unload handler must invoke ProcessModuleUnloadList().
- If _gUefiDriverRevision is not zero and SystemTable->Hdr.Revision is
- less than _gUefiDriverRevision, then return EFI_INCOMPATIBLE_VERSION.
