The only reason why this did not crash until now is because NVKMD_ENGINE_3D
and NVKMD_ENGINE_COMPUTE are always set in the only queue we returned.
With the addition of a video queue, where no state must be submitted, the logic
would try to push an empty push_buffer. This is wrong and the first place where
it fails is when it tries to allocate a BO of size 0 for the push data.
