    streams: Don't bail out when cursor is outside the stream
    
    PipeWire reuses buffers, and buffer metadatas, when streaming. When
    the cursor is moved to outside the stream, the cursor meta also needs
    to be updated, otherwise it'll use the cursor position of whatever is
    in the buffer.
    
    Don't bail out when cursor is outside the stream, and ensure to record
    a metadata-only frame. This only applies to metadata streams.
