Remount /var/lib/docker as --private to fix scaling issue

If an admin mounts all file systems as -rshared (Default on RHEL and Fedora)
we see a scaling problem as the number of container increase.

Basically every new container needs to have it new mounts in /var/lib/docker
shared to all other containers, this ends up with us only able to scale to
around 100 containers, before the system slows down.

By simply bind mounting /var/lib/docker on its and then setting it private,
the scaling issue goes away.

devmapper: Ensure we shut down thin pool cleanly.

The change in commit a9fa1a13c3b0a654a96be01ff7ec19e8009b2094
made us only deactivate devices that were mounted. Unfortunately
this made us not deactivate the base device. Which caused
us to not be able to deactivate the pool.

This fixes that by always just deactivating the base device.
