When the link on the pipewire side is destroyed, on video streams, buffers are removed abruptly and there is no way this pipeline can be revived, so let's post an element error to stop it. On a normal shutdown, the pool is first set to flushing in change_state(), so checking for the flushing state is a good indicator to know if this is a normal shutdown or not. See #1980
