    Fix gin_desc routine to match the WAL format.
    
    In the GIN incomplete-splits patch, I used BlockIdDatas to store the block
    number of left and right children, when inserting a downlink after a split
    to an internal page posting list page. But gin_desc thought they were stored
    as BlockNumbers.
