spi: cs42l43: Make handling missing spk-id GPIOs explicit
gpiod_get_array_optional() for spk-id GPIOs can return NULL, if they are
missing, so do not pass the value to PTR_ERR but instead explicitly
treat NULL as acceptable condition. The old code was correct, but
misleading because PTR_ERR usually is used on errors.

drivers/spi/spi-cs42l43.c:241 cs42l43_get_speaker_id_gpios() warn: passing zero to 'PTR_ERR'
