drm/rockchip: cdn-dp: Fix some error handling paths in cdn_dp_probe()
cdn_dp_audio_codec_init() can fail. So add some error handling.
If component_add() fails, the previous cdn_dp_audio_codec_init() call
should be undone, as already done in the remove function.
Fixes: 88582f564692 ("drm/rockchip: cdn-dp: Don't unregister audio dev when unbinding")
