nilfs2: fix disorder of nilfs_write_super in nilfs_sync_fs
This fixes disorder of nilfs_write_super in nilfs_sync_fs. Commiting super block must be the end of the function so that every changes are reflected. ->sync_fs() is not called frequently so this makes nilfs_sync_fs call nilfs_commit_super instead of nilfs_write_super.
