[PLAT-15282]: fix NPE on k8s operator backup/restore status update

Summary: If any failed backup/restore exists in k8s operator resource, then status update for other b/r restore is failed with NPE as old failed resource does not have status.

Test Plan: Tested manually by creating failed backup which does not have status and veridfied the issue but after this change, b/r status were updated correctly as failed one are skipped.
