nilfs2: super root size should change depending on inode size
The size of super root structure depends on inode size, so NILFS_SR_BYTES macro should be a function of the inode size. This fixes the issue. Even though a different size value will be written for a possible future filesystem with extended inode, but fortunately this does not break disk format compatibility.
