Jason A. Donenfeld 8b3ccbc1f1 treewide: use prandom_u32_max() when possible, part 2

Rather than incurring a division or requesting too many random bytes for
the given range, use the prandom_u32_max() function, which only takes
the minimum required bytes from the RNG and avoids divisions. This was
done by hand, covering things that coccinelle could not do on its own.
