drm/amdkfd: Map wptr BO to GART unconditionally
For simulation C models that don't run CP FW where adev->mes.sched_version
is not populated correctly. This causes NULL dereference in
amdgpu_amdkfd_free_gtt_mem(dev->adev, (void **)&pqn->q->wptr_bo_gart)
and warning on unpinned BO in amdgpu_bo_gpu_offset(q->properties.wptr_bo).
Compared with adding version check here and there,
always map wptr BO to GART simplifies things.
v2: Add NULL check in amdgpu_amdkfd_free_gtt_mem.(Philip)
