[PATCH v2 2/3] virxml: Report error if virXMLFormatMetadata() fails

[Michal Privoznik <mprivozn@xxxxxxxxxx>]

I guess this is more of an academic problem, because if
<metadata/> content was problematic we would have caught the
error during parsing. Anyway, as is this function returns -1
without any error reported. Fix it by reporting one.
