Toke Høiland-Jørgensen 2ead78fbe6 sch_sfb: Also store skb len before calling child enqueue 
[ Upstream commit 2f09707d0c ]

Cong Wang noticed that the previous fix for sch_sfb accessing the queued
skb after enqueueing it to a child qdisc was incomplete: the SFB enqueue
function was also calling qdisc_qstats_backlog_inc() after enqueue, which
reads the pkt len from the skb cb field. Fix this by also storing the skb
len, and using the stored value to increment the backlog after enqueueing.

Fixes: 9efd23297c ("sch_sfb: Don't assume the skb is still around after enqueueing to child")
