MINOR: ssl: improve socket behaviour upon handshake abort.

While checking haproxy's SSL stack with www.ssllabs.com, it appeared that
immediately closing upon a failed handshake caused a TCP reset to be emitted.
This is because OpenSSL does not consume pending data in the socket buffers.
One side effect is that if the reset packet is lost, the client might not get
it. So now when a handshake fails, we try to clean the socket buffers before
closing, resulting in a clean FIN instead of an RST.
