[patch 7/16] s390: fba dasd i/o errors.

From: Horst Hummel <horst.hummel@de.ibm.com>

The FBA discipline does not use retries for failed requests. A request
fails after the first unsuccessful start attempt. There are some rare
conditions (e.g. CIO path recovery) in which the start of an i/o on
a fba device can fail. A tiny amount of retries is therefore
reasonable.
