fdo#56272 SwAnchoredDrawObject::_SetPositioningAttr: fix position

This reverts a part of 51cfbf0c, that is
no longer needed, but causes incorrect drawing objects position.

The problem was that a non-zero position doesn't mean the layout in a
later iteration doesn't change the position, but the referred commit
didn't allow later iterations to fine-tune the position.
