BUG#19318 valgrind: memory leak in ndb_mgmd

2nd part of the patch

fix functions called by ndbd to deal with memory allocation properly. 


ndb/src/mgmapi/mgmapi.cpp:
  in get_configuration() - get a copy to return instead of just passing one back and loosing some memory
ndb/src/mgmsrv/ConfigInfo.cpp:
  clean up after ourselves in constructor
