Commit d2788d34885d4ce5ba ("net: sched: further simplify handle_ing")
removed the call to qdisc_enqueue_root(). However, after this removal
we no longer set qdisc pkt length, which this patch fixes. We make use
of qdisc_pkt_len_init() from 1def9238d4aa ("net_sched: more precise
pkt_len computation"), which was suggested as the current approach so
far does not take into account when GRO builds up GSO packets.

Looks good as quick fix for now. Long term I still want to try to reuse
stats from underlying netdev ;)
For TX we don't have this option and have to do qdisc_pkt_len_init(),
but for RX we should be able to do something smarter.
