[PATCH 6.12 187/231] ASoC: Intel: sof_sdw: Fix unlikely uninitialized variable use in create_sdw_dailinks()

[Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>]

6.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Peter Ujfalusi <peter.ujfalusi@xxxxxxxxxxxxxxx>

commit 4363f02a39e25e80e68039b4323c570b0848ec66 upstream.

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
