nilfs2: fix false warning saying one of two super blocks is broken

Browse Source 
After applying commit b2ac86e1, the following message got appeared
after unclean shutdown:

> NILFS warning: broken superblock. using spare superblock.

This turns out to be a false message due to the change which updates
two super blocks alternately.  The secondary super block now can be
selected if it's newer than the primary one.

This kills the false warning by suppressing it if another super block
is not actually broken.
