drm/amd/display: Only finalize atomic_obj if it was initialized
[ Upstream commit b174084b3fe15ad1acc69530e673c1535d2e4f85 ]
[Why]
If amdgpu_dm failed to initalize before amdgpu_dm_initialize_drm_device()
completed then freeing atomic_obj will lead to list corruption.
[How]
Check if atomic_obj state is initialized before trying to free.
