[PATCH 07/10] virDomainControllerDefParseXML: Remove explicit checks for negative value

[Peter Krempa <pkrempa@xxxxxxxxxx>]

Refactor all cases which use virXMLPropInt and then subsequently check
that the parsed value is not '-1'/negative by using the VIR_XML_PROP_NONNEGATIVE
flag for virXMLPropInt.
