Build Update for ovsrobot/ovn
-------------------------------------

Build: #422
Status: Passed

Duration: 34 mins and 34 secs
Commit: 2dbe9b4 (series_159286)
Author: Numan Siddique
Message: ovn-controller: Don't clear the lflow resources ref during flow_output_run

After the patch [1], which added caching of lflow expr, the lflow_resource_ref
is not rebuilt properly when lflow_run() is called. If a lflow is already cached
in lflow expr cache, then the lflow_resource_ref is not updated.
But flow_output_run() clears the lflow_resource_ref cache before calling lflow_run().

This results in incorrect OF flows present in the switch even if the
address set/port group references have changed.

This patch fixes this issue by not clearing the lflow_resource_ref cache.
This cache gets cleaned up during lflow change handler or in lflow_run().

[1] - 8795bec737b9("ovn-controller: Cache logical flow expr tree for each lflow.")
Fixes: 8795bec737b9("ovn-controller: Cache logical flow expr tree for each lflow.")
