CRI: Fix mount issue in dockershim.

For https://github.com/kubernetes/kubernetes/issues/33189.

The test `Container Runtime Conformance Test container runtime conformance blackbox test when starting a container that exits should report termination message if TerminationMessagePath is set` flakes a lot. (see https://k8s-testgrid.appspot.com/google-node#kubelet-cri-gce-e2e&width=5)

After some investigation, I found the problem is that we are using pointer of iterator.

This fixes the flake.
