AngeloGioacchino Del Regno b1d3db6740 ASoC: mediatek: sof-common: Add NULL check for normal_link string 
[ Upstream commit e3b3ec967a ]

It's not granted that all entries of struct sof_conn_stream declare
a `normal_link` (a non-SOF, direct link) string, and this is the case
for SoCs that support only SOF paths (hence do not support both direct
and SOF usecases).

For example, in the case of MT8188 there is no normal_link string in
any of the sof_conn_stream entries and there will be more drivers
doing that in the future.

To avoid possible NULL pointer KPs, add a NULL check for `normal_link`.
