ASoC: Intel: sof_sdw: Prevent jump to NULL add_sidecar callback

Browse Source 
[ Upstream commit 87cab86925b7fa4c1c977bc191ac549a3b23f0ea ]

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.
