s390/dasd: fix command reject error on ESE devices
Formatting a thin-provisioned (ESE) device that is part of a PPRC copy
relation might fail with the following error:
dasd-eckd 0.0.f500: An error occurred in the DASD device driver, reason=09
[...]
24 Byte: 0 MSG 4, no MSGb to SYSOP
During format of an ESE disk the Release Allocated Space command is used.
A bit in the payload of the command is set that is not allowed to be set
for devices in a copy relation. This bit is set to allow the partial
release of an extent.
Check for the existence of a copy relation before setting the respective
bit.
