libcamera: ipu3: Do not re-queue cancelled buffers
When a video device is stopped all the buffers there queued are released and their state is set to BufferCancelled. Currently, on buffer completion, cancelled buffers are blindly re-queued to the ImgU input or CIO2 output devices, preventing them to be re-started succesfully in future capture sessions. Fix that by inspecting the buffers status and skip re-queueing if they're reported as cancelled. For the ImgU output buffer this is not required, as cancelled request should be reported to applications in order to report them failure of the capture operations.
