ASoC: loongson: Fix error handling in ACPI property parsing

In loongson_card_parse_acpi(), the return value of

device_property_read_string() for the `codec-dai-name` property was

ignored. If the property is missing or invalid, an uninitialized pointer

would be used later, potentially leading to undefined behavior.

Fix this by checking the return value and propagating the error

appropriately. (NVD)
