Stop processing data in QuicSpdyStream::OnDataAvailable() if connection is closed.
If the connection is closed, for example, QuicSpdyStream itself closes it
because a frame of invalid type is received, or because a QPACK error occurs,
then no more data should be fed into HttpDecoder.
gfe-relnote: n/a, change to QUIC v99-only class.
