Should be compliant to spec. Or I should say spec does not under which case the Unregister() should succeed. As long as spec allows Unregister() returns a failure status,
a very low-quality MmCore could always return failure from Unregister().
Our choice here is to return failure for a special case only (Unregister handler B in handler A).
