nilfs2: add /sys/fs/nilfs2/<device> group
This patch adds creation of /sys/fs/nilfs2/<device> group. The <device> group contains attributes that describe file system partition's details: (1) revision - show NILFS file system revision. (2) blocksize - show volume block size in bytes. (3) device_size - show volume size in bytes. (4) free_blocks - show count of free blocks on volume. (5) uuid - show volume's UUID. (6) volume_name - show volume's name.
