Kirk McKusick 5c7ba6bdf8 Fix for tunefs(8) unable to add a UFS/FFS soft update journal.
The reported bug is UFS: bad file descriptor: soft update journaling
can not be enabled on some FreeBSD-provided disk images – failed
to write updated cg.

The UFS library (libufs(3)) failed to reopen its disk descriptor
when first attempting to update a cylinder group. The error only
occurred when trying to add journaling to a filesystem whose first
cylinder group was too full to hold the journal.
