drm/amd/display: don't free stolen console memory during suspend
Don't free the memory if we are hitting this as part of suspend. This way we don't free any memory during suspend; see amdgpu_bo_free_kernel(). The memory will be freed in the first non-suspend modeset or when the driver is torn down.
