Do not bindmount nova-compute directories

Browse Source 
Nova uses a data container.  Data containers are expected to
use the VOLUME keyword and then use volumes_from to access
those volumes.  Throwing in a bindmount to the host filesystem
results in unpredicble behavior, usually in the form of files
being stored on the host filesystem that should be persisted
in the compute data volume.
