This is redundant now, since connectd only sends us this once we tell it it's OK, but that's changing, so clean up now. This means that connectd will be able to make *unsolicited* closes, if it needs to. We share logic with peer_please_disconnect. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
