ext3: fix possible non-initialized variable on htree_dirblock_to_tree()

This is a backport of ext4 commit 90b0a97 which fixes a possible non-initialized variable on htree_dirblock_to_tree(). Ext3 has the same non initialized variable, but, in any case it will be initialized by ext3_get_blocks_handle(), which will avoid the bug to be triggered, but, the non-initialized variable by htree_dirblock_to_tree() is still a bug.
