ofproto-dpif-upcall: Reset ukey's last stats value if the datapath changed.

Browse Source 
When the ukey's action set changes, it could cause the flow to use a
different datapath, for example, when it moves from tc to kernel.
This will cause the the cached previous datapath statistics to be used.

This change will reset the cached statistics when a change in
datapath is discovered.
