net_sched: gen_estimator: account for timer drifts
Under heavy stress, timer used in estimators tend to slowly be delayed
by a few jiffies, leading to inaccuracies.
Lets remember what was the last scheduled jiffies so that we get more
precise estimations, without having to add a multiply/divide in the loop
to account for the drifts.
