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 0abf77e55a2459aa9905be4b226e4729d5b4f0cb
(net_sched: Add accessor function for packet length for qdiscs)
