nfp: flower-tc: add flow stats updates for ct
Add in the logic to update flow stats. The flow stats from the nfp
is saved in the flow_pay struct, which is associated with the final
merged flow. This saves deltas however, so once read it needs to
be cleared. However the flow stats requests from the kernel is
from the other side of the chain, and a single tc flow from
the kernel can be merged into multiple other tc flows to form
multiple offloaded flows. This means that all linked flows
needs to be updated for each stats request.
