net: sched: pie: fix commenting
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"). Signed-off-by: Mohit P.
