Fix a race condition in winbind leading to a crash
When SIGCHLD handling is delayed for some reason, sending a request to a child can fail early because the child has died already. In this case async_main_request_sent() directly called the continuation function without properly removing the malfunctioning child process and the requests in the queue. The next request would then crash in the DLIST_ADD_END() in async_request() because the request pending for the child had been talloc_free()'ed and yet still was referenced in the list. This one is *old*... Volker (cherry picked from commit 8691709626b0d461de91b8fc9d10c730d1f183dd) (This used to be commit c70e2b6476d2d99c79624e15a4a3cfcdc850fc7c)
