This reverts commit 962b3935e44053641764beb0bd095540fe8cbd64.
Reason for revert: Breaks downstream tests.
Original change's description:
> Each spatial layer can only have 1 QP value.
>
> As the code is now, it looks like it accepts that a spatial layer can have more than 1 QP value. These QP values according to the code are summed. However, to my best knowledge this cannot be the case and makes the code hard to read. Therefore, updating it with a check such that it checks that each spatial layer only have 1 QP value and would be easier for a future code reader.
