KAFKA-19464: Remove unnecessary update for find next fetch offset (#20315) 

The PR removes unnecessary updates for find next fetch offset. When the
state is in transition and not yet completed then anyways respective
offsets should not be considered for acquisition. The find next fetch
offset is updated finally when transition is completed.
