ssh: fix flaky TestInvalidServerMessage

When shutting down the test, we sometimes see EOF on the server's side
of the connection and sometimes ECONNRESET. In the latter case, based
on timing, it was possible that the server loop would hit Errorf during
shutdown and cause the test to fail.

LGTM. I've never encountered that condition but it could happen if the listening
socket starts to close before our dial completes. Never hurts to wear double
underpants.
