This is a patch to support second super block of nilfs2.
It will use the second super block when first one is accidentally
collapsed or not synced properly.

NILFS has redundant super blocks.  Those are identical if unmounted cleanly.
However when one of these is collapsed or old, correct one or newer one
should be used to find latest log correctly.

Test on both PPC and x86.
