BUG#21715 mgm client command <id|all> STATUS returns "not connected" for non-data nodes

ndb/src/mgmclient/CommandInterpreter.cpp:
  Adding the judgement for node type to distinguish the data nodes and non-data nodes. 
  From the return value. Management client can't distinguish the really not connected status for data nodes and status of non-data nodes.
  We can get the connect status about non-data nodes from version, if the version is 0, it means no connected status.
