goflow2: zero queue_size means blocking #273

When queue size is zero, automatically set to blocking mode.

After verification, I don't think this is necessary since a non-blocking queue can have a zero size. The only difference is that the first packet is kept in memory when in blocking mode. Non-blocking with zero queue is full real-time. With a queue size of 1, blocking can work on two "old" packets.
