The following patches will change I/O retry to use the same io_path if it is still available. However, bdev_nvme_submit_request() always calls bdev_nvme_find_io_path() first. For I/O retry, if possible, we want to skip calling bdev_nvme_find_io_path() and use nbdev_io->io_path instead. To reuse the code as much as possible and not to touch the fast code path, factor out request submit functions from bdev_nvme_submit_request() into _bdev_nvme_submit_request(). While developing this patch, a bug/mismatch was found such that bdev_io->internal.ch was different from ch of bdev_nvme_submit_request(). Fix it together in this patch.
