Can't create an io2 volume when the requested size is smaller than 4Gi

Saw in 4.17 (but it's not CNV / OCP related)

Always

1. Create a DV/PVC and a first consumer pod

$ cat simple-pvc.yaml 
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: simple-pvc
spec:
  storageClassName: io2-csi
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi


$  cat first-consumer.yaml 
apiVersion: v1
kind: Pod
metadata:
  name: test-pod
spec:
  containers:
    -
      command:
        - sleep
        - "3600000"
      image: "quay.io/fedora/fedora:38"
      imagePullPolicy: IfNotPresent
      name: test-pod
      volumeMounts:
      - mountPath: /foo
        name: data-vol
  volumes:
    -
      name: data-vol
      persistentVolumeClaim:
        claimName: simple-pvc


2. See the PVC describe:

Please specify a volume size above the minimum limit.

PVC is Pending, PV not created 

PVC is Bound, PV size rounded up (to 4Gi is this case)
