hmat acpi: Do not add Memory Proximity Domain Attributes Structure targetting non existent memory.
If qemu is started with a proximity node containing CPUs alone,
it will provide one of these structures to say memory in this
node is directly connected to itself.
This description is arguably pointless even if there is memory
in the node. If there is no memory present, and hence no SRAT
entry it breaks Linux HMAT passing and the table is rejected.
