            Fix flakiness in WebSocket handshake console message.
            https://bugs.webkit.org/show_bug.cgi?id=32598
    
            In chromium, LayoutTests/websocket/tests/handshake-error.html is
            flaky, because it outputs the following console message several times:
              CONSOLE MESSAGE: line 0: Unexpected response code:101
            Update m_mode in WebSocketHandshake correctly: Once it finds
            error in handshake message, set m_mode to Failed and don't try
            reading handshake message again.  If handshake message is not yet
            fully received, set m_mode to Incomplete, so next didReceiveData()
            will try to check handshake message again.
