vmm: Forward device_id from NumaConfig to NumaNode

The device_id field was added to both NumaConfig and NumaNode as part
of the Generic Initiator support, but create_numa_nodes() change
was missed when the commits were reorganized.

As a result, node.device_id is never propogated from the config to
the runtime node and the ACPI SRAT Type 5 (Generic Initiator Affinity)
entries were never emitted.

Add the missing propogation so that create_srat_table() can resolve
the device and emit the correct affinity structure

Fixes: #7717
