Clone volume failed in parallel

This issue was detected when running CSI E2E testsuite `InitProvisioningTestSuite` with test case `should provision storage with pvc data source in parallel`.

To reproduce with k8s e2e framework:
- run test suite `InitProvisioningTestSuite`

To reproduce without k8s e2e framework:
- Provision a PVC `volume-org` with volume mode `block`.
- mount volume `volume-org` on a pod, as a block device.
- in the pod, write some content to this block device.
- delete the pod, but leave the PVC untouched.
-  clone this PVC/volume with 5 replicas at the same time, as `volume-0` through `volume-4`.
- mount each clone to a pod, as block device,
- verify if all clones have the correct content written before.

Actual Result:
- Only the first volume who completed the cloning has the correct content. Other 4 volumes don't have the content. Therefore, test failed.

Expected Result:
- All clones have the correct content
