[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.
