Test Unit Ready translation seems wrong in latest driver

[Sathya Prakash Veerichetty]

The TUR translation returns LUN not ready when the controller is ready in
the latest code whereas in the old code it returns LUN not ready only when
the controller is not ready (proper behavior).

The patch  [PATCH 11/47] nvme: split a new struct nvme_ctrl out of struct
nvme_dev seeded the issue by missing the !.
