ASoC: SOF: ipc4: avoid uninitialized default instance 0

Browse source

When a pipeline contains multiple DAI widgets, the pipe_widget is not
set up except for the first DAI. This result in the pipe_widget having
a default instance 0, which can conflict with another real the
pipeline instance 0 and leads to spurious transitions.

This patch makes sure the instance_id is properly initialized to a
-EINVAL value.
