I don't understand how this works. The HttpNetworkTransaction is associated with
a single request. It then queries the HttpNetworkSession, which queries the
QuicStreamFactory. But the Factory is not associated with a request. It looks
like if there are 2 requests they will both end up getting the same value for
this field, even if one of them does not use QUIC. I think you'll need to move
this logic to something that is per-request (or per stream).
