Jia He f060db9937 ACPI: NFIT: Use fallback node id when numa info in NFIT table is incorrect 
When ACPI NFIT table is failing to populate correct numa information
on arm64, dax_kmem will get NUMA_NO_NODE from the NFIT driver.

Without this patch, pmem can't be probed as RAM devices on arm64 guest:
  $ndctl create-namespace -fe namespace0.0 --mode=devdax --map=dev -s 1g -a 128M
  kmem dax0.0: rejecting DAX region [mem 0x240400000-0x2bfffffff] with invalid node: -1
  kmem: probe of dax0.0 failed with error -22
