block/blkio: Make driver nvme-io_uring take a "path" instead of a "filename"
The nvme-io_uring driver expects a character special file such as /dev/ng0n1. Follow the convention of having a "filename" option when a regular file is expected, and a "path" option otherwise. This makes io_uring the only libblkio-based driver with a "filename" option, as it accepts a regular file (even though it can also take a block special file).
