ofproto-dpif: Refresh stats before ovs-appctl dpif/dump-flows.

As a matter of convenience, this patch refreshes the statistics
when ovs-appctl dpif/dump-flows is called.  Hopefully this will
prevent users from being confused because statistics they were
expecting to see haven't made it from the datapath into the switch
yet.
