Fix freeing old values in index_store_float8_orderby_distances() 6cae9d2c10 has added an error in freeing old values in index_store_float8_orderby_distances() function. It looks for old value in scan->xs_orderbynulls[i] after setting a new value there. This commit fixes that. Also it removes short-circuit in handling distances == NULL situation. Now distances == NULL will be treated the same way as array with all null distances. That is, previous values will be freed if any.
