Fix hash-address bug

The lowest bit of the address was clipped off by wrong use of the mask.
Because of this only even entries could be used, and spoiling of the
key after underpromotion to the 'nearest' alternative would lead to an
enormous number of false hash hits, leading to false result claims.
