drm/amdgpu: Fix __rcu fence pointer accesses
Building for ARCH=um with W=1 C=1 makes sparse report "incompatible
types in comparison expression (different address spaces)" warnings in
the KFD code, exposed after UML builds were enabled:
- amdgpu_amdkfd_fence.c compares the __rcu-annotated dma_fence.ops
pointer directly in to_amdgpu_amdkfd_fence().
- amdgpu_amdkfd_gpuvm.c compares the __rcu eviction fence pointer
directly in amdgpu_amdkfd_gpuvm_restore_process_bos().
Fixes: af3f2f5db265 ("drm/amdgpu: Remove UML build exclusion from Kconfig")
