Error description
A non-CHPIDV guest reset allegience CCW causes an unneccessary broadcast to other members of the SSI when the data indicates that a reserve is held elsewhere. This is unnecessary for a non-CHPIDV guest and the data from the X'44' CCW issued on the guest's system should be used as the final result.
