Fix error recovery in scsi_interpret_sense(). It turns out that ERESTART
wasn't getting sent back for most errors, even if there were retries left
on the command. I'm not sure how I ever let this slip by before...
In any case, we now send back ERESTART if there are retries left for the
command, and send back the default error code when there are no retries
left.
