This simplifies sd_spinup_disk so scsi-ml retries errors for it. Note that we retried specifically on a UA and also if scsi_status_is_good returned failed which could happen for all check conditions, so in this patch we don't check for only UAs. We do not handle the outside loop's retries because we want to sleep between tried and we don't support that yet.
