This patch corrects a problem in scsi error handling.

When a device is offlined indicated by a message like ...Device offlined
- not ready...

the command return status was not being updated with a failure status if
the IO was a timeout.

I tested the patch on system with ips, aic, and qlogic fc adapters, but
was unable to generate a satisfactory device offline test case.

I did test this fix on uml with scsi_debug and generated a device
offline condition with verified this fix was working correctly.
