tdf#115023 Check mpControlData for nullptr

Control::ImplClearLayoutData happens to be called post
dispose, but Control::dispose already destroyed
mpControlData. So put back the nullptr check that was
removed in e8b49f09074fe184374bee5062715357427ae044
("new loplugin: useuniqueptr: vcl").

(But IMHO it's odd that we even try to send lose focus
events to disposing windows. So maybe it would make sense
to replace the "! pOldFocusWindow->IsDisposed()" check
inside Window::ImplGrabFocus with "isDisposed()" which
comes from VclReferenceBase, and set much earlier?)
