Update to deal with the fact that the INDEX_FL code in the ext2 2.4
code accidentally had the INDEX_FL backwards compatibility code
removed.   E2fsck will now fix HTREE corruptions in preen mode, and
mke2fs will not create filesystems with the dir_index flag set
by default.  (The user has to specifically request it.)
