mbedtls_ssl_handshake_free: take the SSL context as argument

Browse source 
Change the signature of mbedtls_ssl_handshake_free again. Now take the
whole SSL context as argument and not just the configuration and the
handshake substructure.

This is in preparation for changing the asynchronous cancel callback
to take the SSL context as an argument.
