xenconfig: fix conversion of <driver> to backendtype
When converting domXML to xen xl.cfg, backendtype should
not be emitted if <driver> is not specified. Moreover,
<driver name='file'/> should be converted to backendtype
qdisk, similar to handling of <driver> in libxlMakeDisk()
in libxl_conf.c.
Prior to this change, connectDomainXMLToNative would
produce incorrect xl.cfg when the input domXML contained
<driver name='file'/>
domXML:
<disk type="file" device="disk">
<driver name="file"/>
<source file="/image/file/path"/>
<target dev="xvda" bus="xen"/>
</disk>
virsh domxml-to-native xen-xl domXML
disk = [ "format=raw,vdev=xvda,access=rw,backendtype=target=/image/file/path" ]
xl create xl.cfg
config parsing error in disk specification: unknown value
for backendtype: near `target=/image/file/path' in
`format=raw,vdev=xvda,access=rw,backendtype=target=/image/file/path'
