When the client adapter is configured in passthrough mode, the stream param changed event in pipewire-pulse is emitted before the session manager creates the link, and not after. Therfore, the peer can never be found when replying create stream, and the pulseaudio application receives a stream error. This patch delays the create stream reply until the link is added if the peer cannot be found, fixing the above race conditon to allow passthrough mode to work with pulseaudio applications.
