**What this PR does / why we need it**:

Clean code of petset, from:

```
func (p *apiServerPetClient) getPVC(pvcName, pvcNamespace string) (*api.PersistentVolumeClaim, bool, error)
```

to:

```
func (p *apiServerPetClient) getPVC(pvcName, pvcNamespace string) (*api.PersistentVolumeClaim, error) 
```

I think the 2nd(bool type) return value of [getPVC](https://github.com/kubernetes/kubernetes/blob/master/pkg/controller/petset/pet.go#L228) is unnecessary, as the caller can be responsible for checking the error type and tell if it exists via the [error type](https://github.com/kubernetes/kubernetes/blob/master/pkg/controller/petset/pet.go#L231-L233).

So, I remove the 2nd return value of `getPVC()`.

The benefit of this change is that we can simplify the code of `getPVC()` while don't increase the caller's code.
