PATCH: fix qdisc return code

[Jamal Hadi Salim]

The little discussion going on reminds me of this other patch i was
sitting on. Patrick made the last changes to this area.
Dave please apply if ACK from Patrick.


cheers,
jamal

The mapping between TC_ACTION_SHOT and the qdisc return codes is better
suited to NET_XMIT_BYPASS so as not to confuse TCP
