[libvirt PATCH v3 2/5] conf: refactor virDomainResourceDefParse

[Pavel Hrdina <phrdina@xxxxxxxxxx>]

There is no need to error out for empty <partition></partition> element
as we can just simply ignore it. This allows to simplify the function
and prepare it for new sub-elements of <resource>.

It makes the <partition> element optional so we need to reflect the
change in schema as well.
