dpif-netdev: Pass Openvswitch other_config smap to dpif.

Browse Source 
Currently we parse the 'other_config' column in Openvswitch table in
bridge.c.  We extract the values (just 'pmd-cpu-mask' for now) and we
pass them down to the datapath, via different layers.

If we want to pass other values to dpif-netdev.c (like we recently
discussed) we would have to touch ofproto.c, ofproto-dpif.c and dpif.c.

This patch sends the entire other_config column to dpif-netdev, so that
dpif-netdev can extract the values it's interested in.

No functional change.
