old bug in htree_dirblock_to_tree()

Both ext3 and ext4 htree_dirblock_to_tree() is just filling
the in-core rbtree for use by call_filldir().  All updates of
->f_pos are done by the latter; bumping it here (on error) is obviously
wrong - we might very well have it nowhere near the block we'd found
an error in.
