[PATCH] ext3: htree memory leak fix

From Alex Tomas

We started using ext3_dx_readdir() for all dir_index filesystems, because
we want to return entries in hash order always, so that readdir with a
partial read + new entry added before next readdir won't be crazy.

So we now need to free the structure at filp->pricate_data even against
non-indexed directories.
