Fix: distance test to include all existing nodes

The previous implementation did not consider memory-less nodes as numa_num_configured_nodes() returns only nodes with memory and numa_node_size() check is unnecessary for distance check. Hence removed the check for memory. Signed-off-by: Harish <harish@linux.vnet.ibm.com>
