+++ This bug was initially created as a clone of Bug #2038679 +++

Description of problem:
When cloning with volume mode file system, using storage API fails due to resizing.

Version-Release number of selected component (if applicable):
4.10

How reproducible:
100%

Steps to Reproduce:
1. Create DV with file system, using storage api:

apiVersion: cdi.kubevirt.io/v1alpha1
kind: DataVolume
metadata:
name: <dv name>
annotations:
cdi.kubevirt.io/storage.bind.immediate.requested: "true"
spec:
storage:
resources:
requests:
storage: 38Gi
storageClassName: hostpath-provisioner
source:
http:
url: <os image>

2. Create clone

apiVersion: cdi.kubevirt.io/v1beta1
kind: DataVolume
metadata:
name: dest-dv
spec:
source:
pvc:
name: <DV NAME>
namespace: <DV NAMESPACE>
storage:
resources:
requests:
storage: 38Gi
storageClassName: hostpath-provisioner
contentType: kubevirt

Actual results:
clone fails:
The request is invalid: spec.source.PVC: target resources requests storage size is smaller than the source

Expected results:
DV created.

Additional info:
Same clone using PVC API pass
