drm/amd/amdgpu: add check that shadow page directory is GPU-accessible
Skip amdgpu_gem_va_update_vm when shadow the page directory is swapped out. Clean up the check for non-shadow BOs as well using the new helper function. This fixes a crash with the stack trace: amdgpu_gem_va_update_vm -> amdgpu_vm_update_page_directory -> amdgpu_ttm_bind -> amdgpu_gtt_mgr_alloc Signed-off-by: Nicolai Hähnle <nicolai.haehnle@amd.com> Reviewed-by: Chunming Zhou <david1.zhou@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
