Stefan Weinhuber 6cc7f16895 [S390] dasd: forward internal errors to dasd_sleep_on caller 
If a DASD requests is started with dasd_sleep_on and fails, then the
calling function may need to know the reason for the failure.
In cases of hardware errors it can inspect the sense data in the irb,
but when the reason is internal (e.g. start_IO failed) then it needs
a meaningfull return code.
