ofproto: Handle OpenFlow version mismatch for requestforward with groups.
OpenFlow 1.4+ supports a feature called requestforward. When a controller
enables this feature, the switch sends that controller a copy of other
controllers' group and meter modification requests. OpenFlow 1.5 supports
some group features not in OpenFlow 1.4. When OVS attempted to forward
such requests to an OpenFlow 1.4 controller, it reported an error and
exited. This commit fixes the problem by making OVS properly translate the
messages to OpenFlow 1.4 format.
