storage e2e: fix volume metric test for generic ephemeral volume
This is a fix for the new test case from https://github.com/kubernetes/kubernetes/pull/105636 which had to be merged without prior testing due to not having a cluster to test on and no pull job which runs these tests. https://testgrid.k8s.io/sig-storage-kubernetes#gce-serial then showed a failure. The fix is simple: in the ephemeral case, the PVC name isn't set in advance in pvc.Name and instead must be computed. The fix now was tested on a kubetest cluster in GCE.
