btrfs: fix perms on demonstration debugfs interface
btrfs provides a helpful demonstration of how to export a global variable via debugfs; however, it is unique among other debugfs files in that it is world-writable, which causes some concern to people who are not familiar with its purpose. Fix it so that it is only user-writable. Signed-off-by: Eric Sandeen <sandeen@redhat.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
