S390 dasd: fix data size for PSF/PRSSD command
commit 49fd38bdaa96f093fcad3176a781a4d0de8f8602 upstream The Perform Subsystem Function/Prepare for Read Subsystem Data command requires 12 bytes of parameter data, but the respective data structure dasd_psf_prssd_data has a length of 16 bytes. Current storage servers ignore the obsolete bytes, but older models fail to execute the command and report an incorrect length error. This causes the device initilization for these devices to fail. To fix this problem we need to correct the dasd_psf_prssd_data structure and shorten it to the correct length.
