3 more commits in main of changes to UFS/FFS superblock checks, possibly no longer rejecting your case

One of the things changed is the test you have seen fail
that I recently replicated a failure via using just main
9aa02d5120a :

-	CHK(fs->fs_csaddr, !=, cgdmin(fs, 0), %jd);

It has been replaced with later code:

+	cgnum = dtog(fs, fs->fs_csaddr);
+	CHK(fs->fs_csaddr, <, cgdmin(fs, cgnum), %jd);

So there is a chance that the rejected file systems
will no longer be rejected.

I've got other builds going on and will will be a while
before I can update to have this material involved to
test it.
