    Include all network devices in nova diagnostics
    
    get_instance_diagnostics expected all interfaces
    to have a <target> element with a "dev" attribute in
    the instance XML. This is not the case for VFIO
    interfaces (<interface type="hostdev">).
    This caused an IndexError when looping over
    the interfaces.
    
    This patch fixes this issue by retrieving interfaces
    data directly from the guest XML and adding nics
    appropriately to the diagnostics object.
