Commit42cdf6f687("drm/amdgpu/gfx8: always restore kcq MQDs") made the ring pointer always to be reset on resume from suspend. This caused compute rings to fail since the reset was done without also resetting it for the firmware. Reset wptr on the GPU to avoid a disconnect between the driver and firmware wptr.
