Kyle MeyerandGreg Kroah-Hartman 9956d4892e x86/platform/uv: Handle deconfigured sockets ...

commit 1f6aa5bbf1 upstream.

When a socket is deconfigured, it's mapped to SOCK_EMPTY (0xffff). This causes
a panic while allocating UV hub info structures.

Fix this by using NUMA_NO_NODE, allowing UV hub info structures to be
allocated on valid nodes.
