drm/amdkfd: change SDMA MQD memory type
SDMA MQD memory type is NC that causes MQD data overwritten accidentally by an old stable cache line. Changing it to UC default for GART will fix the issue. The mqd_gfx9 parameter is meant for control stacks that are allocated together with user mode queue MQDs. Setting mqd_gfx9 to true maps the control stack pages as NC. Here it was accidentally applied to SDMA MQDs, which are allocated together with the HIQ MQD. Setting the mqd_gfx9 to false avoids that.
