    libata: clear TF before IDENTIFYing · 81afe893

    Some devices chock if Feature is not clear when IDENTIFY is issued.
    Set ATA_TFLAG_ISADDR | ATA_TFLAG_DEVICE for IDENTIFY such that whole
    TF is cleared when reading ID data.
    
    Kudos to Art Haas for testing various futile patches over several
    months and Mark Lord for pointing out the fix.
