sch_red: fix red_calc_qavg_from_idle_time
[ Upstream commit ea6a5d3b97b768561db6358f15e4c84ced0f4f7e ]
Since commit a4a710c4a7490587 (pkt_sched: Change PSCHED_SHIFT from 10 to
6) it seems RED/GRED are broken.
red_calc_qavg_from_idle_time() computes a delay in us units, but this
delay is now 16 times bigger than real delay, so the final qavg result
smaller than expected.
Use standard kernel time services since there is no need to obfuscate
them.
