Control explicit command queue management capability bit based on scheduling mode. Capability will be available only when hardware scheduling mode is set. There is no point of allowing user space to create and destroy command queues with OS schedling mode because FW does not support all required functionalities for correct command queue management with OS scheduling. Return -ENODEV from command queue create/destroy/submit IOCTLs.
