Riccardo Mancini 2d6b74baa7 perf map: Fix dso->nsinfo refcounting ... 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.
