revised it to resolve some issues and to simplify the core change by
improving the patch organization.
changes from v5:

This moves out section that updates information of the recent log
position stored in super blocks from nilfs_commit_super to a new

This function checks validity of super block pointers.
If first super block is invalid, it will swap the super blocks.
The function should be called before any super block information updates.
Caller must obtain nilfs-ns_sem.

This will sync super blocks in turns instead of syncing duplicate
super blocks at the time. This will help searching valid super root
when super block is written into disk before log is written, which is
happen when barrier-less block devices are unmounted
