ALSA: hda/ca0132 - Fix memory leak at error path

The CA0132 codec driver doesn't call the free function at its error path of the probe, which leaves the allocated memory. Call ca0132_free() properly at the error handling. Fixes: a73d511 ("ALSA: hda/ca0132: Add unsol handler for DSP and jack detection") Signed-off-by: Takashi Iwai <[email protected]>
