ext2fs: temporarily disable htree directory index.
Our code does not consider yet the case of hash collisions. This
is a rather annoying situation where two or more files that
happen to have the same hash value will not appear accessible.
The situation is not difficult to work-around but given that things
will just work without enabling htree we will save possible
embarrassments for the next release.
