    libata: implement and use ATA_QCFLAG_QUIET · e027bd36

    Implement ATA_QCFLAG_QUIET which indicates that there's no need to
    report if the command fails with AC_ERR_DEV and set it for passthrough
    commands.
    
    Combined with previous changes, this now makes device errors for all
    direct commands reported directly to the issuer without going through
    EH actions and reporting.
    
    Note that EH is still invoked after non-IO device errors to determine
    the nature of the error and resume command execution (some controller
    requires special care after error to continue).  It just performs
    default maintenance after error, examines what's going on, realizes
    that it's none of its business and reports the command failure without
    logging any error messages.
