vkd3d-shader/hlsl: Avoid member access on NULL resource load (ubsan).

In some scenarios this resource load is NULL, and we are still doing
&load->node on it.

    vkd3d/libs/vkd3d-shader/hlsl.c:2195:12: runtime error: member access
            within null pointer of type 'struct hlsl_ir_resource_load'

This happens in tests/hlsl/sampler-state.shader_test, in the following
test:

    [pixel shader fail]
    Texture2D tex;

    float4 main(): sv_target
    {
        return tex.Sample(sampler_state {}, float2(0, 0));
    }
