scsi: scsi_error: Handle power-on reset unit attention
As per SAM there is a status precedence, with any sense code 29/XX taking second place just after an ACA ACTIVE status. Additionally, each target might prefer to not queue any unit attention conditions, but just report one. Due to the above, this will be that one with the highest precedence. This results in the sense code 29/XX effectively overwriting any other unit attention. Hence we should report the power-on reset to userland so that it can take appropriate action.
