ASoC: audio-graph-card2: call of_node_get() before of_get_next_child()
commit c6f597bc598a8 ("ASoC: audio-graph-card2: remove unneeded
of_node_get()") removed of_node_get(), but it need to keep original
reference, so of_node_get() itself is needed.
Because of_get_next_child() will call of_node_put() inside, if the
reference count dropped to zero, then of_node_get() after that will be
use afer free. Need to call of_node_get() *before* that.
