T6021: Fix QoS shaper r2q calculation
The current calculation `r2q` is wrong as it uses `Floor division` but expecting `division` This way `math.ceil` calculate wrong value as we expect round a number upward to its nearest integer For example for speed 710 mbits expected value `444` but we get `443` ``` from math import ceil MAXQUANTUM = 200000 speed = 710000000 speed_bps = int(speed) // 8 >>> speed_bps // MAXQUANTUM 443 >>> speed_bps / MAXQUANTUM 443.75 >>> >>> >>> ceil(speed_bps // MAXQUANTUM) 443 >>> ceil(speed_bps / MAXQUANTUM) 444 >>> ``` (cherry picked from commit ce1035e1e8642bf740e2a21693a72fe2127b8f72)
