It looks like the problem is that cg_initediblk is corrupted in one of
the cylinder groups. It should never be larger than fs_ipg, and pass5()
silently enforces this limit. We could do the same in pass1(), except
that if it ever got set to too small a value, such as 0, fsck would
think a bunch of files were missing.
