Remove redundant deficits updates

Originally, deficit updates were introduced as part of
adding support for exclusion bounds in the power distribution
algorithm. However, it was primarily for reasoning purposes,
and these updates have no actual effects.
Only the distributed_power requires updating and the
deficit updates were safely removed.
