pkt_sched: Fix return value corruption in HTB and TBF.
Based upon a bug report by Josip Rodin. Packet schedulers should only return NET_XMIT_DROP iff the packet really was dropped. If the packet does reach the device after we return NET_XMIT_DROP then TCP can crash because it depends upon the enqueue path return values being accurate. Signed-off-by: David S. Miller <davem@davemloft.net>
