Fix a crash of accessing deleted paintengine
When painting to QPixmap with QBlitterPaintEngine and dfb
PaintEngine have PaintDevice (pdev) as QImage. Painter code
uses PaintDevice::paintEngine() to refer to paintEngine.
This will became dangling pointer since QDirectFbBlitter::doLock()
will delete QImage. Instead return QPixmap as PaintDevice.
