virtio: rng: add derating factor for use by hwrng core
The khwrngd thread is started when a hwrng device of sufficient
quality is registered. The virtio-rng device is backed by the
hypervisor, and we trust the hypervisor to provide real entropy.
A malicious or badly-implemented hypervisor is a scenario that's
irrelevant -- such a setup is bound to cause all sorts of badness, and a
compromised hwrng is the least of the user's worries.
Given this, we might as well assume that the quality of randomness we
receive is perfectly trustworthy. Hence, we use 100% for the factor,
indicating maximum confidence in the source.
