ASoC: meson: axg-card: fix null pointer dereference in clean up
When using modern dai_link style, we must first make sure the
struct snd_soc_dai_link_component exists before accessing its members.
In case of early probe deferral, some of the '.cpus' or '.codecs' may not
have been allocated yet. Check this before calling of_node_put() on the
structure member.
