sch_teql: should not dereference skb after ndo_start_xmit()

It is illegal to dereference a skb after a successful ndo_start_xmit()
call. We must store skb length in a local variable instead.

Bug was introduced in 2.6.27 by commit f27fcb2b99982bb12c5cc0f5bed64548cfef4ac7
(net_sched: Add accessor function for packet length for qdiscs)
