ASoC: simple-card: Dereference pointer for memcpy sizeof in asoc_simple_card_probe

ASoC: simple-card: Dereference pointer for memcpy sizeof in asoc_simple_card_probe

Commit 4fb7f4df49d3 ("ASoC: simple-card: use cpu/codec pointer on
simple_dai_props") updated {cpu,codec}_dai to be pointers in struct
simple_dai_props but didn't update these locations to dereference the
pointers.
This patch fixup it for non DT simple-card use case.
