Fix: correct boolean assignment in fn update_congestion_signals

[okoklaile]

self.loss_in_round = false; //according to ietf,it should be set to false.
//see:https://www.ietf.org/archive/id/draft-cardwell-iccrg-bbr-congestion-control-02.html#name-updating-the-model-upon-pac
//BBRUpdateCongestionSignals():
// BBRUpdateMaxBw()
// if (rs.losses > 0)
// BBR.loss_in_round = 1
// if (!BBR.loss_round_start)
// return /* wait until end of round trip */
// BBRAdaptLowerBoundsFromCongestion()
// BBR.loss_in_round = 0
