e2e: CephFS data validation fails when deployed with Helm

[nixpanic]

Describe the bug

When the CephFS e2e tests run on Ceph Tentacle (v20), they always fail during

check data persist after recreating pod

Disabling that test, causes failure at an other one:

create RWX clone from ROX PVC

With standard yaml deployment, the e2e tests succeed. With Ceph Reef (v19) and Helm, the e2e tests succeed.
