ASoC: amd: amd_sdw: Fix unlikely uninitialized variable use in create_sdw_dailinks()

Browse Source 
Initialize current_be_id to 0 in AMD legacy stack(NO DSP enabled) SoundWire
generic machine driver code 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.
