    rdp-pipewire-stream: Also clear pending frame, when destroying stream
    
    Currently, when the PipeWire stream is destroyed, there could still be
    a pending frame, that won't be encoded any more.
    In such case, the frame data is leaked.
    
    So, fix this by freeing the pending frame data, when the stream is
    destroyed.
