Orivej Desh 667fe3f3f3 Fix oob_tcp tcp_component_close segfault with active listeners ... oob_tcp in non-HNP mode shares libevent event_base with oob_base [1]. orte_oob_base_close calls: (1) oob_tcp component_shutdown, then (2) opal_progress_thread_finalize, then (3) oob_tcp tcp_component_close [2]. opal_progress_thread_finalize calls tracker_destructor [3] that frees the event_base [4]. If any oob_tcp event listeners are active at this time, oob_tcp will crash trying to delete them at [5] [6]. This change moves oob_tcp event listener cleanup from component_close to component_shutdown so that it happens before the event_base is freed.
