'policy ls' command does not show the name of the volume using that policy

========================================

Steps are as follows:

1. Created a vsan storage policy using the following command:
   /usr/lib/vmware/vmdkops/bin/vmdkops_admin.py policy create --name some-policy --content '(("proportionalCapacity" i0)("hostFailuresToTolerate" i0)'

[root@sc2-rdops-vm03-dhcp-97-99:~] /usr/lib/vmware/vmdkops/bin/vmdkops_admin.py policy ls

Policy Name Policy Content Active

---

some-policy (("hostFailuresToTolerate" i0) ("forceProvisioning" i0)) Unused

Active column shows unused since no volume is using this policy.

2. Created a volume named some-vol using the above created policy:
   docker volume create --driver=vmdk --name=some-vol -o vsan-policy-name=some-policy

Docker inspect for the created volume shows name of the policy used by the volume

root@photon-TX4FfW2ET [ ~/docker-volume-vsphere ]# docker volume inspect some-vol | grep "Name|vsan-policy-name"
"Name": "some-vol",
"vsan-policy-name": "some-policy"

3. 'policy ls' command still shows policy as unused:

[root@sc2-rdops-vm03-dhcp-97-99:~] /usr/lib/vmware/vmdkops/bin/vmdkops_admin.py policy ls
Policy Name Policy Content Active

---

some-policy (("hostFailuresToTolerate" i0) ("forceProvisioning" i0)) Unused

==================================

Ideally we should see the name of the virtual disks using the policy should show up in the Active column.

I have narrowed down the root cause to be in vmdk_utils.list_vmdks() method. Please focus on this method to fix the issue.
