    AHCI - Fix embarassing bug for non-NCQ disk accesses > 128G
    Fix an embarassing bug for non-NCQ disk accesses > 128G.  This only
    applied to non-NCQ accesses for disks which effectively means disks
    behind a PM, since NCQ is generally used everywhere else.  Accesses
    for seek positions from 128G to 2TB were wrapping the LBA.
