Subject: [PATCH 1/7] Fix: node_list with memory-less nodes

Patch adds check to avoid memory-less nodes while traversing till

max node, and this also prevents nodes_to_use sysmalloc failure as

nodes_to_use is malloc'ed with numa_num_configured_nodes which

returns the number of nodes configured with memory.
