Bruno Faccini 7c734ad868 mm/fake-numa: handle cases with no SRAT info 
commit 4c80187001 upstream.

Handle more gracefully cases where no SRAT information is available, like
in VMs with no Numa support, and allow fake-numa configuration to complete
successfully in these cases

Link: https://lkml.kernel.org/r/20250127171623.1523171-1-bfaccini@nvidia.com
Fixes: 63db8170bf (“mm/fake-numa: allow later numa node hotplug”)
