[Bug]: Error in shift operation and arithmetic operation

[adcen0107]

What happened?

在xqc_cubic.c的xqc_cubic_update函数实现中，line 66 ~ 70：
/*
* t = elapsed_time * 1024 / 1000000, convert microseconds to milliseconds,
* multiply by 1024 in order to be able to use bit operations later.
*/
t = (now + cubic->min_rtt - cubic->epoch_start) << XQC_CUBIC_TIME_SCALE / XQC_MICROS_PER_SECOND;

结合注释和上下文逻辑，很明显编码者相要的实现是
t =( (now + cubic->min_rtt - cubic->epoch_start) << XQC_CUBIC_TIME_SCALE) / XQC_MICROS_PER_SECOND;
所以，当前实现是一个bug。

Steps To Reproduce

查看xqc_cubic.c的xqc_cubic_update函数源码或添加打印。
