xkb: XkbSendGeometry(): pass in struct as value instead of pointer 

The function doesn't need to pass anything back via this pointer, it's
the last consumer of this struct. Make understanding the code a bit easier
and clear the road for further simplifications by passing the struct as
value instead of pointer.
