Failed to create flow entries which change UDP destination port.

OpenFlow plugin failed to create flow entries which change UDP destination port.
I observed this issue in the latest distribution build in the stable/lithium branch.

I saw the following WARN message when I tried to install a flow entry which contained an action modify UDP destination port.
