Requeue instead of throwing an error when onwer of kind can't be found

[vishesh92]

Issue #, if available:
#299
Description of changes:
This pull request includes improvements to error handling in both the reconciliation process and the affinity group checking function. The most important changes are:

Error handling improvements:

• controllers/utils/base_reconciler.go: Added a check for a specific error message when getting the owner of a kind and requeue the request with the error message if the owner is not found.
• test/e2e/common.go: Added error handling when retrieving an affinity group by ID, ensuring that the test fails with a descriptive error message if the retrieval fails.

Looks good! Maybe we can add a unit test?
