Description of problem:
[Alibaba CSI] volume with parameter readonly:true inside storageclass.yaml, allowing to write inside volume and in describe volume getting displayed 2 times where the values are not same

Version-Release number of selected component (if applicable):
oc get clusterversion
NAME VERSION AVAILABLE PROGRESSING SINCE STATUS
version 4.11.0-0.nightly-2022-04-12-000004 True False 7h36m Cluster version is 4.11.0-0.nightly-2022-04-12-000004

How reproducible:
Always

Steps to Reproduce:
1) Install Alibaba cluster
2) Create storageclass with readonly parameter: true

3) Check the pod,pvc status
4) Describe the pv and check the output, which is displaying as
pv.Readonly: false,
pv.VolumeAttributes.readOnly: true

oc describe pv
Source:
Type: CSI (a Container Storage Interface (CSI) volume source)
Driver: diskplugin.csi.alibabacloud.com
FSType:
VolumeHandle: d-0xih57sbz0ht38636k6t
ReadOnly: false
VolumeAttributes: readOnly=true storage.kubernetes.io/csiProvisionerIdentity=1649737828224-8081-diskplugin.csi.alibabacloud.com
type=cloud_essd
Events: <none>

5) Write down inside volume and able to write data successfully.
vi writebl.sh
depname="mydep-csi-659ff8cf7c-gms6f"
namespace="testdisk"

oc exec $depname -n $namespace -i – sh -c "bin/dd if=/dev/null of=/dev/dblock bs=512 count=1"
oc exec $depname -n $namespace -i – sh -c "echo 'testdata' > /dev/dblock"
oc exec $depname -n $namespace -i – sh -c "/bin/dd if=/dev/dblock of=/tmp/testfile bs=512 count=1"
oc exec $depname -n $namespace -i – sh -c "cat /tmp/testfile"

Execution:
./writebl.sh
0+0 records in
0+0 records out
0 bytes copied, 3.5926e-05 s, 0.0 kB/s
1+0 records in
1+0 records out
512 bytes copied, 4.8309e-05 s, 10.6 MB/s
testdata

Actual results:
Able to write inside volume successfully and describe pv showing 2 readonly values
pv.Readonly: false,
pv.VolumeAttributes.readOnly: true

Expected results:
It should not allow to write data inside volume.
