Volume unmount failed after docker restart #1724

Description

Setup: Datastore name had spaces e.g. DS name: 'shared Vmfs - (10)'

Test steps:

1. Created a volume.
2. Ran a container with volume mounted.
3. While container is running, killed the docker.
4. Unmounting failed after docker restart.

Logs have been attached at the end.

Test steps and their output are as follows:

  1. Created a volume on a datastore "shared Vmfs - (10)"
root@sc-rdops-vm02-dhcp-52-237:~# docker volume create -d vsphere --name 'TestXXXX@shared   Vmfs   - (10)'
TestXXXX@shared   Vmfs   - (10)
root@sc-rdops-vm02-dhcp-52-237:~#
root@sc-rdops-vm02-dhcp-52-237:~# docker volume ls

vsphere:latest      TestXXXX@shared   Vmfs   - (10)
  1. Ran a container with volume mounted
root@sc-rdops-vm02-dhcp-52-237:~# docker run -d -v 'TestXXXX@shared   Vmfs   - (10)':/vol1 busybox tail -F /dev/null
