processLayers()

In older files (before Krita 5.2.7) we used to save the layer offset into the XML metadata, while loading the pixel data at the origin. Since 5.2.7 we stopped saving offsets (we save null instead of them), we let's just make sure we don't load garbage from older files).

Hence, we pass false for loading the offset
