nilfs2: fix disorder of nilfs_write_super in nilfs_sync_fs

Browse Source 
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.
