ASan reports a memory leak of nsinfo during the execution of: # perf test "31: Lookup mmap thread". The leak is caused by a refcounted variable being replaced without dropping the refcount. This patch makes sure that the refcnt of nsinfo is decreased whenever a refcounted variable is replaced with a new value.
