soundwire: stream: separate alloc and config within sdw_stream_add_xxx()

Browse source

Separate alloc and config parts so that follow-up patches can allow
for multiple calls to sdw_stream_add_slave/master. This is a feature
from the ALSA/ASoC frameworks which is not supported today.

This is an invasive patch which modifies the error handling flow, with
cleanups only done when an allocation fails. Configuration failures
only return an error code.
