hugetlb: use only nodes with memory for huge pages
Register per node hstate sysfs attributes only for nodes with memory.
Global replacement of 'all online nodes" with "all nodes with memory" in
mm/hugetlb.c. Suggested by David Rientjes.
A subsequent patch will handle adding/removing of per node hstate sysfs
attributes when nodes transition to/from memoryless state via memory
hotplug.
NOTE: this patch has not been tested with memoryless nodes.
