flush() is a TX related function

[JAndrassy]

WiFiClient.flush should send all data from tx buffer. it is not true that in Arduino world it is a rx buffer thing. the Client class is inherited from Print class and the flush method is from Print. And in Print implementations the flush is a tx thing. And the reference for the Client class implementation is Ethernet library.
