ata: libata: exclude FUA support for known buggy drives 

Thread [1] reported back in 2012 problems with enabling FUA for 3
different drives. Add these drives to ata_device_blacklist[] to mark
them with the ATA_HORKAGE_NO_FUA flag. To be conservative and avoid
problems on old systems, the model number for the three new entries
are defined as to widely match all drives in the same product line.
