OK, not keen on the way you're setting req->errors.

Our big problem with FS requests is deferred or corrected errors
(basically we never want the FS to think we had a problem with them).  I
think it's currently OK because block tends to believe the returned
error code rather than req->errors ... I'd just hate it if that changed
and suddenly lots of stuff broke.

I think you're just looking for the sense data, so could you look at
that and not set req->errors?
