ufs: make solaris fsck happy
Alex Viskovatoff let me know that after copying data to solaris's ufs from
linux, solaris's fsck sees some errors in cylinder summary information.
This is because of solaris expects find some data on another places, then
curernt implementation save it. This patch fixes this issue. It is
tested by me, and also Alex reported that it works for him.
