Ignore "SshException: Already closed" errors

These occur when the client disappears in the middle of us writing
data out to them.  There really isn't an error on our side, just
some lame user who disconnected before he received everything he
requested.  Silence the error from our logs by checking for it and
skipping out, without logging.
