[libvirt] [PATCH] Make virDomainGetXMLDesc output cache settings even if no special driverName is set

If a special cache strategy for a disk has been specified in a domain definition, but no driverName has been set, virDomainGetXMLDesc will not include the <driver> tag at all. This patch makes sure that the <driver> tag is included if any of the settings it can contain has been set.
