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

Han-Wen Nienhuys b2aa35443f ssh: drop extra connection Close call in TestMuxReadWrite 
The extra Close call runs in a separate goroutine, and races with the
deferred Close call, leading to test flakes if the extra call fails

Han-Wen Nienhuys 9e7f5dc375 x/crypto/ssh: interpret disconnect message as error in the transport layer. 
This ensures that higher level parts (e.g. the client authentication
loop) never have to deal with disconnect messages.
