Erick Tryzelaar 279210d13f ssh: don't err out on channel request msgs to unknown channels ...

rfc4254 section 5.4 states that channel request messages sent to an
unrecognized channel should be replied with a `SSH_MSG_CHANNEL_FAILURE`,
rather than erring out and closing the mux. This can occur with servers
like openssh-portable, which can begin to close a channel and also use
that channel for keepalives before it has received a closed response
from the client.

Fixes golang/go#38908
