Rik van Riel 217ece6129 KVM: use yield_to instead of sleep in kvm_vcpu_on_spin ...

Instead of sleeping in kvm_vcpu_on_spin, which can cause gigantic
slowdowns of certain workloads, we instead use yield_to to get
another VCPU in the same KVM guest to run sooner.

This seems to give a 10-15% speedup in certain workloads.
