Fix for excess creation of QWindow instances. 

topData() is called from various functions for any kind of widgets,
not just for top-levels. Therefore createTLSysExtra cannot assume
that the widget is top-level. Previously QWindows were created
for desktop widget, toolbars, mdi subwindows, etc. which is
wrong. The patch will avoid this, and will also fix drawing
isses when dragging mdi windows.
