Fix containers mounting issue. With the current v9 patches if a container
hierarchy is mounted and then umounted. A second mount of the hierarchy
fails
Steps to reproduce the problem
1. mount -t container container /<mnt point>
2. umount /<mnt point>
3. mount -t container container /<mnt point>
Step 3 fails with -EBUSY. This is due to the fact that when we unmount,
in container_put_super(), we need to delete the current root from the roots
list.
The patch below fixes the issue
