'struct hmm_mirror' is not defined without the Kconfig option set,
so we cannot include it within another struct:

In file included from drivers/gpu/drm/amd/amdgpu/../amdgpu/amdgpu.h:72:
drivers/gpu/drm/amd/amdgpu/../amdgpu/amdgpu_mn.h:69:20: error: field has incomplete type 'struct hmm_mirror'
        struct hmm_mirror       mirror;
                                ^
drivers/gpu/drm/amd/amdgpu/../amdgpu/amdgpu_mn.h:69:9: note: forward declaration of 'struct hmm_mirror'
        struct hmm_mirror       mirror;

Add the #ifdef around it that is also used for all functions operating
on it.
