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.
