x86/uv: fix init of memory-less nodes

Browse source

Add support for nodes that have cpus but no memory.
The current code was failing to add these nodes
to the nodes_present_map.

v2: Fixes case caught by David Rientjes - missed support
    for the x2apic SRAT table.

[ Impact: fix potential boot crash on memory-less UV nodes. ]
