[S390] dasd: enable prefix independent of pav support
The DASD device driver needs to explicitly enable the prefix command on the storage server, before it can be used. Originally we enabled this command along with others only if we wanted to support PAV. However, today we require this command for other features like High Performance FICON as well, so we need to always enable prefix.
