idpf: set scheduling mode for completion queue
The HW must be programmed differently for queue-based scheduling mode.
To program the completion queue context correctly, the control plane
must know the scheduling mode not only for the Tx queue, but also for
the completion queue.
Unfortunately, currently the driver sets the scheduling mode only for
the Tx queues.
Propagate the scheduling mode data for the completion queue as
well when sending the queue configuration messages.
Fixes: 1c325aac10a8 ("idpf: configure resources for TX queues")
