if you make numa_info QOM object node_memdev link<> property,
then above hunk could be replaced with just setting link.
And node_mem could be replaced with readonly property that reads size
directly from memdev avoiding data duplication.
As side-effect it numa_info will also become accessible for introspection
using QOM interface. Something like:
qom-list /machine/memory-node[X]
qom-get /machine/memory-node[X]/memory_size
