ALSA: hda: cs35l56: Remove redundant call to hda_cs_dsp_control_remove()

The driver doesn't create any ALSA controls for firmware controls, so it
shouldn't be calling hda_cs_dsp_control_remove().

commit 34e1b1bb7324 ("ALSA: hda: cs35l56: Stop creating ALSA controls for
firmware coefficients") removed the call to hda_cs_dsp_add_controls() but
didn't remove the call for destroying those controls.
