crypto/ssh: don't send the last auth failure message if disconnecting

If we are going to send the disconnect message and close the connection,
because we have exhausted the number of authentication attempts, don't
send the final authentication failure message. This behavior matches
that of OpenSSH.

Fixes golang/go#51149
