nvme: refactor ns->ctrl by request
Just for current code in nvme_cleanup_cmd(), we don't have to get
namespace instance, but we need controller instance.
Controller instance can be retrieved by namespace instance, but it can
be directly accessed by nvme_request instance from request.
ctrl = nvme_req(req)->ctrl;
We don't have to go around namespace instance from request instance
through gendisk.
