ASoC: Intel: sof_sdw: Fix unlikely uninitialized variable use in create_sdw_dailinks()
Initialize current_be_id to 0 to handle the unlikely case when there are
no devices connected to a DAI.
In this case create_sdw_dailink() would return without touching the passed
pointer to current_be_id.
Found by gcc -fanalyzer
