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.
