rocker: set FDB cleanup timer according to lowest ageing time
In rocker, ageing time is a per-port attribute, so the next time the FDB cleanup timer fires should be set according to the lowest ageing time. This will later allow us to delete the BR_MIN_AGEING_TIME macro, which was added to guarantee minimum ageing time in the bridge layer, thereby breaking existing behavior.
