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

commit 6b83ba4bc3ecb915476d688c9f00f3be57b49a0c upstream.

Initialize current_be_id to 0 in SOF based AMD generic SoundWire machine
driver 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.
