KVM: x86: pass kvm_vcpu to kvm_read_guest_virt and kvm_write_guest_virt_system
commit ce14e868a54edeb2e30cb7a7b104a2fc4b9d76ca upstream.
Int the next patch the emulator's .read_std and .write_std callbacks will
grow another argument, which is not needed in kvm_read_guest_virt and
kvm_write_guest_virt_system's callers. Since we have to make separate
functions, let's give the currently existing names a nicer interface, too.
Fixes: 129a72a0d3c8 ("KVM: x86: Introduce segmented_write_std", 2017-01-12)
