drm/amdgpu/gfx11: Avoid uninitialised variable 'index' 



This stops clang complaining:

drivers/gpu/drm/amd/amdgpu/gfx_v11_0.c:376:6: warning: variable 'index' is used uninitialized whenever 'if' condition is true [-Wsometimes-uninitialized]
        if (ring->is_mes_queue) {
            ^~~~~~~~~~~~~~~~~~
drivers/gpu/drm/amd/amdgpu/gfx_v11_0.c:433:30: note: uninitialized use occurs here
        amdgpu_device_wb_free(adev, index);
                                    ^~~~~
drivers/gpu/drm/amd/amdgpu/gfx_v11_0.c:376:2: note: remove the 'if' if its condition is always false
        if (ring->is_mes_queue) {
        ^~~~~~~~~~~~~~~~~~~~~~~~~
drivers/gpu/drm/amd/amdgpu/gfx_v11_0.c:364:16: note: initialize the variable 'index' to silence this warning
        unsigned index;
                      ^
                       = 0
