Reduce redundant Nodes().List() call

Browse Source 
dumpAllNodeInfo() called Nodes().List() internally, but the function
is called from DumpAllNamespaceInfo() only and DumpAllNamespaceInfo()
calls Nodes().List() before calling dumpAllNodeInfo().
So this makes the result of Nodes().List() being passed to
dumpAllNodeInfo() then reduce a call of Nodes().List().
