ASoC: cs35l56: Fix out-of-bounds in dev_err() in cs35l56_read_onchip_spkid()

Remove the incorrect use of onchip_spkid_gpios[i] in the dev_err() after
regmap_read() of CS35L56_GPIO_STATUS1 returns an error.

This dev_err() was incorrectly copy-pasted from one inside the for-loop,
where i was valid. The read of CS35L56_GPIO_STATUS1 isn't for a specific
GPIO register, so the use of onchip_spkid_gpios[i] in the error message is
both irrelevant and out-of-bounds here.
