Subject: [PATCH] conf: use virXMLFormatElement() in
c480ed
 virDomainDeviceInfoFormat()

In order to add zPCI child element for PCI address, we update
c480ed
virDomainDeviceInfoFormat() to format device info by helper function
c480ed
virXMLFormatElement(). Then we could simply format zPCI address into
c480ed
child buffer later.
