* Associate NUMA node specified by @props.node_id with cpu slots that

* which would affect all cpu slots that match it.
* Ex for pc machine:
* -smp 4,cores=2,sockets=2 -numa node,nodeid=0 -numa node,nodeid=1 \
* -numa cpu,node-id=0,socket_id=0 \
* -numa cpu,node-id=1,socket_id=1
* will assign all child cores of socket 0 to node 0 and
* of socket 1 to node 1.
*
* On attempt of reassigning (already assigned) cpu slot to another NUMA node,
* return error.
* Empty subset is disallowed and function will return with error in this case.
