pipeline: raspberrypi: Avoid multiple opens of Unicam embedded data node
It is possible for the application to call pipeline_handler::configure() multiple times, which would attempt to open the Unicam embedded data node on every call. This would cause a warning message as the node would have already been opened. Avoid this by tracking if the node has previously been opened. Note that this is a temporary fix since the open call for the Unicam embedded data node will be moved from pipeline_handler::configure() to pipeline_handler::match().
