Fix two netem bugs :
1) When a frame was dropped by tfifo_enqueue(), drop counter was incremented twice.
2) When reordering is triggered, we enqueue a packet without checking queue limit. This can OOM pretty fast when this is repeated enough, since skbs are orphaned, no socket limit can help in this situation.
