[libvirt] [PATCHv2 07/62] Revert "qemu: monitor: Add the 'query-nodes' argument for query-blockstats"

[Peter Krempa]

Turns out that 'query-nodes' is not what we want and the
'query-blockstats' command was in fact buggy. Revert the new field since
it's not needed.

This reverts commit 50edca1331298bfcb2622e8fe588d493aff9ab68.
