If the geom has an offset, it is eliminated and the geom is
repositioned at the body's position. If the geom has no offset,
this function does nothing.
This is more efficient than calling dGeomSetOffsetPosition(zero)
and dGeomSetOffsetRotation(identiy), because this function actually
eliminates the offset, rather than leaving it as the identity transform.
@param geom the geom to have its offset destroyed.
