Adding/deleting SI in chain results in traffic loss.

Problem:
While re-evaluating flow/rflow the old reverse flow of flow/rflow were not
pointing to same(pointing to NULL) and hence were marked as short flow,
but same was not updated to stats_collector. This resulted in flow dangling till
aging and in turn holding respective VRF in deleted state. Afet aging VRF was
removed and new VRF added, in turn restoring traffic.

Solution:
Notify stats collector on marking as short flow.
