crypto: never return zero in random32_unbiased
...
This avoids problems when the caller can't deal with a zero
walue, which happens often enough that it's worth nipping the
problem in the bud.

Cryptonight variant 2
...
Contains two modifications to improve ASIC resistance: shuffle and integer math.
Shuffle makes use of the whole 64-byte cache line instead of 16 bytes only, making Cryptonight 4 times more demanding for memory bandwidth.
Integer math adds 64:32 bit integer division followed by 64 bit integer square root, adding large and unavoidable computational latency to the main loop.
