[PATCH] s390: fba dasd i/o errors
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.
