Marshaling any discriminated union (flat union) into JSON overflows the stack

[connorkuehl]

To reproduce:

package main

import (
	"encoding/json"
	"os"

	"github.com/digitalocean/go-qemu/qmp/raw"
)

func main() {
	s := "libvirt-1-format"
	opts := raw.BlockdevOptionsNBD{NodeName: &s}
	_ = json.NewEncoder(os.Stdout).Encode(opts)
}

output

runtime: sp=0xc0201603f8 stack=[0xc020160000, 0xc040160000]
