Since commit 8a0a9bd4db, this comment in mmap_rnd() does not
hold true as the value returned by get_random_int() will in fact be
different every single call. Remove the comment and simplify the code
back to its original desired form.
This reverts commit a5adc91a4b which is no longer necessary and
also fixes the sparc code that copied this same adjustment.
