Handle SSL_do_handshake() being called before SSL_provide_quic_data().
If SSL_do_handshake() is called before SSL_provide_quic_data() has been
called, the QUIC read buffer will not have been initialised. In this case
we want to return TLS13_IO_WANT_POLLIN so that the QUIC stack will provide
handshake data.
