[libvirt] [PATCH 11/12] test: qemu: json: Avoid using the now obsolete functions

[Peter Krempa]

Use the new single function instead of calling
qemuMonitorJSONGetBlockStatsInfo and
qemuMonitorJSONGetBlockStatsParamsNumber. This will allow to delete the
functions later while still maintaining coverage.
