NVMe: Implement namespace list scanning
The NVMe 1.1 specification provides an identify mode to return a list of active namespaces. This is more efficient to discover which namespace identifiers are active on a controller, providing potentially significant improvement in scan time for controllers with sparesly populated namespaces.

To be relaxed later] Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@fb.com>
