net: sched: do not requeue a NULL skb
[ Upstream commit 3dcd493fbebfd631913df6e2773cc295d3bf7d22 ]
A failure in validate_xmit_skb_list() triggered an unconditional call
to dev_requeue_skb with skb=NULL. This slowly grows the queue
discipline's qlen count until all traffic through the queue stops.
We take the optimistic approach and continue running the queue after a
failure since it is unknown if later packets also will fail in the
validate path.
Fixes: 55a93b3ea780 ("qdisc: validate skb without holding lock")
