I'm not entirely sure that all static analyzers will be able to see that
'name' and 'mode'...

... will not be uninitalized if virXMLPropEnum returns since
VIR_XML_PROP_REQUIRED is used, but the code is correct.

The removed function was checking '<= 0' thus VIR_XML_PROP_NONZERO is
missing.

Don't break the line here. 80 cols is not a hard limit.
