s390/dasd: add safe offline interface
The regular behavior of the DASD device driver when setting a device offline is to return all outstanding I/O as failed. This behavior is different from that of other System z operating systems and may lead to unexpected data loss. Adding an explicit 'safe' offline function will allow customers to use DASDs in the way they expect them to work.
