scsi: error: alua: I/O errors for ALUA state transitions

When a host is configured with a few LUNs and I/O is running, injecting
FC faults repeatedly leads to path recovery problems.  The LUNs have 4
paths each and 3 of them come back active after say an FC fault which
makes 2 of the paths go down, instead of all 4. This happens after
several iterations of continuous FC faults.

Reason here is that we're returning an I/O error whenever we're
encountering sense code 06/04/0a (LOGICAL UNIT NOT ACCESSIBLE, ASYMMETRIC
ACCESS STATE TRANSITION) instead of retrying.
