ScatterChartItem: do not use item's position when resizing marker

The existing code was using current marker's coordinates when updating
its size, but that actually resulted in double offset, because later
we are explicitly calling setPos() on the marker.
Fix it by always using (0, 0) as an offset when calculating the
marker's rectangle.

Fixes: QTBUG-112904
