MINOR: tools/rnd: compute the result outside of the CAS loop ha_random64() uses a DWCAS loop to produce the random, but it computes the resulting value inside the loop while it doesn't change upon success, so this is a needless overhead inside the critcal path that participates to making threads fail the race and try again. Let's take the value out of the loop.
