    NetConfigDevice: set bond down before configuration
    
    When NM is running on a machine and lnst is using normal configuration
    the bond is created, NM sets it up which makes the configuration of the
    bonding mode fail. This patch makes sure that before configuring any
    options the device is down. It's a temporary workaround until the issue
    is fixed in NM.
