[PATCH] Correct return type of hashfn() in fs/dquot.c

  CC      fs/dquot.o
fs/dquot.c:208: warning: type qualifiers ignored on function return type

Once again with extra gcc warnings enabled.  Every user of the function is
expecting unsigned value, not int in first place, and I think the const is
just misplaced.
