[libvirt] [PATCH 1/3] Make startmode optional in toplevel interface definitions.

[laine@xxxxxxxxx]

From: Laine Stump <laine@xxxxxxxxx>

The minimal XML returned from ncf_if_xml_state() doesn't contain this
attribute (which makes no sense in the case of reporting current
status of the interface), and it was preventing it from passing
through the parse/format step.
