When error happen in multifd_send_thread, it use error_copy to set migrate error in
multifd_send_terminate_threads(). We should call error_free after it.
Similarly, fix another two places in multifd_recv_thread/multifd_save_cleanup.
The leak stack:
Direct leak of 48 byte(s) in 1 object(s) allocated from:
