[PATCH net-next v4 07/10] net: sched: pie: fix commenting

[gautamramk@gmail.com]

From: "Mohit P. Tahiliani" <tahiliani@nitk.edu.in>

Fix punctuation and logical mistakes in the comments.
The logical mistake was that "dequeue_rate" is no longer
the default way to calculate queuing delay and is not
needed. The default way to calculate queue delay was
changed in commit cec2975f2b70 ("net: sched: pie:
enable timestamp based delay calculation").
