qemu-img info never uses ImageInfo's backing-image field, because it opens the backing chain one by one with BDRV_O_NO_BACKING, and prints all backing chain nodes' information consecutively. Use BlockNodeInfo to make it clear that we only print information about a single node, and that we are not using the backing-image field. Notably, bdrv_image_info_dump() does not evaluate the backing-image field, so we can easily make it take a BlockNodeInfo pointer (and consequentially rename it to bdrv_node_info_dump()). It makes more sense this way, because again, the interface now makes it syntactically clear that backing-image is ignored by this function.
