Adjust the VSI/Aggregator layers based on the number of logical layers
supported by the FW. Currently the VSI and Aggregator layers are
fixed based on the 9 layer scheduler tree layout. Due to performance
reasons the number of layers of the scheduler tree is changing from
9 to 5. It requires a readjustment of these VSI/Aggregator layer values.
