[Amrith Kumar]

My recent change

https://github.com/openstack/trove/commit/b668e85cb6d8d147fde22e2b43897ea2cc024db0

introduced a problem. Not sure why I didn't catch it sooner but just hit this problem.

https://github.com/openstack/trove/blame/master/trove/guestagent/volume.py#L93-L94

 LOG.debug("Formatting %s. Executing: %s.",
  (self.device_path, cmd))

Yeah, no. That's wrong.
