Fix handling of APIserver errors when saving provisioned PVs.

When API server crashes *after* saving a provisioned PV and before sending
200 OK, the controller tries to save the PV again. In this case, it gets
AlreadyExists error, which should be interpreted as success and not as error.

Especially, a volume that corresponds to the PV should not be deleted in the
underlying storage.

Fixes #44372
