ASoC: loongson: fix error codes in loongson_card_parse_acpi()

The acpi_node_get_property_reference() function returns kernel error
codes and not ACPI error codes.  So, although it does not affect the
compiled code, using the ACPI_FAILURE() macro is wrong.  Secondly,
if the is_acpi_device_node() function returns false, then we should
return -ENOENT instead of returning success.
