ASoC: Intel: sof_sdw: Prevent jump to NULL add_sidecar callback
In create_sdw_dailink() check that sof_end->codec_info->add_sidecar
is not NULL before calling it.
The original code assumed that if include_sidecar is true, the codec
on that link has an add_sidecar callback. But there could be other
codecs on the same link that do not have an add_sidecar callback.
Fixes: da5244180281 ("ASoC: Intel: sof_sdw: Add callbacks to register sidecar devices")
