Fixes CVE-2026-56855 Fixes golang/go#81317
ch.msg is only read while the channel open or a channel request with a
reply is pending, so anything the default arm of channel.handlePacket
delivered to it was never consumed. The blocking send there let a
misbehaving peer fill the buffer with well-formed but unexpected message
types carrying a valid channel id and stall the mux read loop,
deadlocking the whole connection.
No conforming peer sends such messages during the connection protocol.
Treat them as a protocol error and tear the connection down, as
handleUnknownChannelPacket already does for the same messages when the
channel id is not in use.
