We have two flags, DASD_FLAG_DEVICE_RO and DASD_FEATURE_READONLY, that
tell us whether a device is read-only. DASD_FLAG_DEVICE_RO is set when a
device is attached as read-only to z/VM and DASD_FEATURE_READONLY is set
when either the corresponding kernel parameter is configured, or the
read-only state is changed via sysfs.
This is valuable information in any case. However, only the feature flag
is being checked at the moment when we display the current state.
Fix this by checking both flags.
