ALSA: hda: cs35l41: Correct error condition handling

Browse source 
commit 943f4e64ee upstream.

Function cs_dsp_coeff_write_ctrl() can return 3 possible values:
0 - no change, 1 - value has changed and -1 - error, so positive value
is not an error.
Fixes: 7406bdbc4f ("ASoC: wm_adsp: Return whether changed when writing controls")
