Disk image size data are not contained in the reply of query-blockstats but need to be gathered from query-block. For use with -blockdev we really need to call 'query-named-block-nodes' and process it to retrieve the correct data.
This patch introduces qemuMonitorBlockStatsUpdateCapacityBlockdev which updates the capacity data by nodename rather than device name.
