SCSI command completion path bumps ioerr_cnt whenever scsi_cmd->result isn't zero; unfortunately, this means that non-error sense reporting bumps the counter too. This is pronounced with ATA passthrough commands because most of them explicitly request the resulting taskfile to be transported via sense data bumping the count unconditionally. Don't bump the counter if scsi_cmd->result simply indicates that sense data is available.
