mem-ruby: fixed SimpleNetwork starvation
The round-robing scheduling seed is shared across all ports and vnets
in the router and it's possible that, under certain heavy traffic
scenarios, the same port will always fill the input buffers before any
other port is checked.
This patch removes the round-robin scheduling. The port to be checked
first is always the one with the oldest message.
