[PATCH 5/9] qemu: Accept <allowReboot value='default'/>

[Andrea Bolognani]

Up until a few commits ago, libvirt produced this XML and so
we need to be able to read it back to prevent a bunch of

  error : virXMLPropEnumInternal:516 : XML error: Invalid value
  for attribute 'value' in element 'allowReboot': 'default'

messages from being logged on daemon upgrade when there are
running guests.
