Followup on https://github.com/kubernetes/kubernetes/pull/111846. This particular test was left out from that PR because once it was enabled it started failing. It was desired to merge https://github.com/kubernetes/kubernetes/pull/111846 irrespective of this particular test. The failure in the test was caused due to the `createFSGroupRequestPreHook` mock CSI driver hook function assuming that the request object passed to it is an instance of the respective struct, but it's actually a pointer instead. This resulted in the hook function not fulfilling its purpose, and the so the test failed.
