We will name the lower level objects starting with nvme_* and the upper level objects starting with nvme_bdev_*. This object is a channel per ctrlr and another new channel will be added on top of this object. Rename nvme_io_path by nvme_ctrlr_channel based on the new naming rule. nvme_io_path will be used for a new object which is used to find an optimal I/O path and to reset multiple ctrlrs sequentially when multipath is supported.
