random32: add __init prefix to prandom_start_seed_timer

We only call that in functions annotated with __init, so add __init prefix in prandom_start_seed_timer() as well, so that the kernel can make use of this hint and we can possibly free up resources after it's usage. And since it's an internal function rename it to __prandom_start_seed_timer().
