* Checks only for fatal/no/recover error.
* A detailed examination of the sense data is done later outside
* the interrupt handler.
*
* The logic is based on the 'IBM 3880 Storage Control Reference' manual
* 'Chapter 7. 9336 Sense Data'.
*
* RETURN VALUES
* dasd_era_none no error
* dasd_era_fatal for all fatal (unrecoverable errors)
* dasd_era_recover for all others.
