The XML format used for QEMU capabilities is not required to be stable across releases, as we invalidate the cache whenever the libvirt binary changes. We none the less always try to parse te entire XML file before we do any validity checks. Thus if we change the format of any part of the data, or change permitted values for enums, then libvirtd logs will be spammed with errors. These are not in fact errors, but an expected scenario. This change makes the loading code validate the cache timestamp against the libvirtd timestamp immediately. If they don't match then we stop loading the rest of the XML file.
