pc-bios/s390-ccw: Do not bail out early if not finding a SCSI disk

Browse source 
In case the user did not specify a boot device, we want to continue
looking for other devices if there are no valid SCSI disks on a virtio-
scsi controller. As a first step, do not panic in this case and let
the control flow carry the error to the upper functions instead.
