cli: Fix xml output for volume statusv3.5.2beta1

The XML output for volume status was malformed when one of the nodes is
down, leading to outputs like
-------
          <node>
             <node>
               <hostname>NFS Server</hostname>
               <path>localhost</path>
               <peerid>63ca3d2f-8c1f-4b84-b797-b4baddab81fb</peerid>
               <status>1</status>
               <port>2049</port>
               <pid>2130</pid>
             </node>
-----

This was happening because we were starting the <node> element before
determining if node was present, and were not closing it or clearing it
when not finding the node in the dict.

To fix this, the <node> element is only started once a node has been
found in the dict.
