Eric Dumazet 36b7bfe09b netem: fix possible NULL deref in netem_dequeue() ...

commit aec0a40a6f ("netem: use rb tree to implement the time queue")
added a regression if a child qdisc is attached to netem, as we perform
a NULL dereference.

Fix this by adding a temporary variable to cache
netem_skb_cb(skb)->time_to_send.
