Description of problem:
Not READYTOUSE volumesnapshot instance can not be deleted

Version-Release number of selected component (if applicable):
$ oc get clusterversion --context=admin
NAME      VERSION                             AVAILABLE   PROGRESSING   SINCE   STATUS
version   4.5.0-0.nightly-2020-05-30-025738   True        False         5h41m   Cluster version is 4.5.0-0.nightly-2020-05-30-025738


How reproducible:
Always

Steps to Reproduce:
1. Deploy aws ebs csi drvier wih operator, the storageclass gp2-csi is created too.
$ oc get sc gp2-csi
NAME      PROVISIONER       RECLAIMPOLICY   VOLUMEBINDINGMODE      ALLOWVOLUMEEXPANSION   AGE
gp2-csi   ebs.csi.aws.com   Delete          WaitForFirstConsumer   true                   19h
2. Create a default volumesnapshotclass with:
$ cat volumesnapshotclass.yaml 
apiVersion: snapshot.storage.k8s.io/v1beta1
kind: VolumeSnapshotClass  
metadata:
  name: csi-aws-ebs-snapclass
deletionPolicy: Delete
3. Create a PVC with storageclass gp2-csi(pvc in pending status)
$ cat pvc.yaml 
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: pvc2
spec:
  storageClassName: gp2-csi
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 2Gi
4.Create a volumesnapshot with:
$ cat volumesnapshot.yaml 
apiVersion: snapshot.storage.k8s.io/v1beta1
kind: VolumeSnapshot
metadata:
  name: mysnap2
spec:
  volumeSnapshotClassName: csi-aws-ebs-snapclass
  source:
    persistentVolumeClaimName: pvc2
5. Check the volumesnapshot
$ oc get volumesnapshot mysnap2
NAME      READYTOUSE   SOURCEPVC   SOURCESNAPSHOTCONTENT   RESTORESIZE   SNAPSHOTCLASS           SNAPSHOTCONTENT   CREATIONTIME   AGE
mysnap2   false        pvc2                                              csi-aws-ebs-snapclass                                    17h
6. Create a Pod using pvc2(pvc in bound status)
7. Create a volumesnapshot for pvc2 again
$ cat volumesnapshot.yaml 
apiVersion: snapshot.storage.k8s.io/v1beta1
kind: VolumeSnapshot
metadata:
  name: mysnap3
spec:
  volumeSnapshotClassName: csi-aws-ebs-snapclass
  source:
    persistentVolumeClaimName: pvc2
8. Check the volumesnapshot status and delete volumesnapshot mysnap2 and mysnap3


Actual results:
mysnap3 volumesnapshot(can be delete successfully):
Status:
  Bound Volume Snapshot Content Name:  snapcontent-fd1c7ddb-d911-4dd6-a359-d3e015d4b9b0

  Restore Size:                        2Gi
Events:                                <none>



mysnap2 volumesnapshot(can not be deleted):
Status:
  Error:
    Message:     Failed to create snapshot content with error failed to get input parameters to create snapshot mysnap2: "the PVC pvc2 is not yet bound to a PV, will not attempt to take a snapshot"
    Time:        2020-06-01T09:51:05Z
  Ready To Use:  false
Events:          <none>



Expected results:
mysnap2 volumesnapshot can be deleted successfully.
