libcamera: pipeline_handler: Cancel Request on queueing failure
Capture requests are queued by the PipelineHandler base class to each pipeline handler implementation using the virtual queueRequestDevice() function. However, if the pipeline handler fails to queue the request to the hardware, the request gets silently deleted from the list of queued ones, without notifying application of the error. Reporting to applications that a Request has failed to queue by cancelling and then completing it allows applications to maintain their request-tracking mechanism consistent with the one internal to the library.
