drm/amdgpu:fix waiting on dirty fence if bo->shadow is NULL (race issue:BO shadow was just released and gpu-reset kick in but BO hasn't yet) recover_vram_from_shadow won't set @next, so the following "fence=next" will wrongly use a fence pointer which may already dirty. fixing it by set next to NULL prior to recover_vram_from_shadow Signed-off-by: Monk Liu <Monk.Liu@amd.com> Reviewed-by: Chunming Zhou<david1.zhou@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
