drm/amd/display: Only finalize atomic_obj if it was initialized

Browse source

[ Upstream commit b174084b3f ]

[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.
