[S390] dasd: let recovery cqr inherit flags from failed cqr
The usual way to recover a failed DASD ECKD request (cqr) is to create a new request with an appropriate recovery CCW program. Certain features, e.g. failfast, can be enabled per request and are stored in the requests flags. These flags have to be copied from the failed to the recovery request, to let the recovery request use the same features as the original one.
