net/sched: sch_cake: fixup cake_mq rate adjustment for diffserv config

Browse source

cake_mq's rate adjustment during the sync periods did not adjust the
rates for every tin in a diffserv config. This lead to inconsistencies
of rates between the tins. Fix this by setting the rates for all tins
during synchronization.
