btrfs-progs: mkfs: Use the whole file or block device to mkfs for rootdir
For --rootdir, even for large existing file or block device, it will always shrink the resulting filesystem. The problem is, mkfs.btrfs will try to calculate the dir size, and use it as @block_count to mkfs, which makes the filesystem shrunk. Fix it by trying to get the original block device or file size as @block_count, so mkfs.btrfs can use the full file/block device for --rootdir option.
