tsocket: make sure we delete the fd event before calling close()
We got random double free errors, when getting events from epoll_wait() and try to dereference the private talloc pointer attached to it. Before doing the close() in the tstream_disconnect_send() function we need to delete the fd event. commit 38f505530ba06323a56c7d3914630efffcd12629 only fixed it for tdgram sockets. metze
