pkt_sched: Fix return value corruption in HTB and TBF.
[ Upstream commit 69747650c814a8a79fef412c7416adf823293a3e ]
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.
