nilfs2: add /sys/fs/nilfs2/<device>/checkpoints group
This patch adds creation of /sys/fs/nilfs2/<device>/checkpoints group. The checkpoints group contains attributes that describe details about volume's checkpoints: (1) checkpoints_number - show number of checkpoints on volume. (2) snapshots_number - show number of snapshots on volume. (3) last_seg_checkpoint - show checkpoint number of the latest segment. (4) next_checkpoint - show next checkpoint number.
