[PATCH] winemac: Fix z-ordering between two child (owned) windows of the same parent (owner).

[Ken Thomases]

The window being ordered was first put in the correct place and then was moved
to the other end of the children list by the loop that was intended to adjust
the windows strictly between the window and the ancestor.
