kvm: Fix eflags corruption in kvm mode
This should explain a lot of the weird breakages of upstream KVM we've
seen recently (actually we should have seen it much earlier):
Stop translating eflags into TCG format when in kvm mode as we never
translate it back and rather sync this broken state into the kernel.
