While this shouldn't be needed if all devices that claim that they support NCQ autosense (ata_id_has_ncq_autosense()) and/or the sense data reporting feature (ata_id_has_sense_reporting()), actually supported those features. However, there might be some old ATA devices that either have these bits set, even when they don't support those features, or they simply return malformed data when using those features. These devices should be quirked, but in order to try to minimize the impact for the users of these such devices, it was suggested by Damien Le Moal that it might be a good idea to sanity check the sense data received from the device. If the sense data looks bogus, then the sense data is never added to the scsi_cmnd command. Introduce a new function, ata_scsi_sense_is_valid(), and use it in all places where sense data is received from the device.
