Bernie Harris df3eb6cd68 net_sched: drr: check for NULL pointer in drr_dequeue
There are cases where qdisc_dequeue_peeked can return NULL, and the result
is dereferenced later on in the function.

Similarly to the other qdisc dequeue functions, check whether the skb
pointer is NULL and if it is, goto out.
