du: avoid spurious warnings with 64-bit gcc -W
Problem reported by Jim Meyering in:
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=6524#74
* gl/lib/di-set.c (di_ent_hash): Rework so that the compiler does
not incorrectly warn about shifting by 64-bits in unreachable code.
* gl/lib/ino-map.c (ino_hash): Likewise.
