Add missing repaintManager check
This is likely a problem only after the 6.4 changes to move QQuickWidget
composition from OpenGL to QRhi.
Add an extra check to the condition when bailing out.
In QWidgetPrivate (qwidget.cpp) all similar calls into the
repaintManager are guarded by
if (tlwExtra && tlwExtra->backingStore && tlwExtra->repaintManager)
therefore it makes sense to perform the same check in the other file too.
The assumption is that the check was not added here due to being outside
of qwidget.cpp.
