PluginView::platformGetValue() won't dereference null pointer when plugin asks for NPNVnetscapeWindow and no graphicsview is present none

When using a QGraphicsWebview in a scene that is not viewed by any graphicsview, webkit will crash when the plugin asks for NPNVnetscapeWindow. If there is no graphicsview (client->ownerWidget() returns 0, see patch), asking for NPNVnetscapeWindow should return 0.
