Jan Höppner 7e64db1597 s390/dasd: Add discard support for ESE volumes 
ESE (Extent Space Efficient) volumes are thin-provisioned and therefore
space is only occupied with real data. In order to make previously used
space available for re-allocation again, discard support is enabled for
ESE volumes allowing the DASD driver to release said space.
