Automatic merge from submit-queue

deletePod handler in the deployment controller shouldn't set owner refs

**What this PR does / why we need it**:
This PR stops the deletePod handler in the deployment controller from adopting replica sets when determining if a deployment needs to be requeued. It leaves this logic to the replication loop, removing the replica set adoption side effect.

**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #46933 

**Special notes for your reviewer**:
@kargakis PR for delete pod handler setting owner refs issue
