Repeated call to ios->exit(ios); was observed as used after free using asan. Only call it once: In the exit handler. Always call the exit handler and check there whether listenonly is set and there skip resetting the terminal if so. Do not reset the terminal elsewhere. Do not call the exit handler from the quit command, just call exit, invoking the signal handler too. Signed-off-by: Jonas Rebmann <jre@pengutronix.de>
