ASoC: samsung: odroid: fix a double-free issue for cpu_dai 
The cpu_dai variable is still being used after the of_node_put() call,
which may result in double-free:

        of_node_put(cpu_dai);            ---> released here

        ret = devm_snd_soc_register_card(dev, card);
        if (ret < 0) {
...
                goto err_put_clk_i2s;    --> jump to err_put_clk_i2s
...

err_put_clk_i2s:
        clk_put(priv->clk_i2s_bus);
err_put_sclk:
        clk_put(priv->sclk_i2s);
err_put_cpu_dai:
        of_node_put(cpu_dai);            --> double-free here
