When calculating an unevennes error we must include planned moves. When move is planned in redpanda the allocation is only added to the replicas that are about to be added to the replica set but not removed from the one that are removed during partition reallocation. Fixed calculation of unevenness error by subtracting removed replicas on the nodes they are moved from. Fixes: redpanda-data#9507 Signed-off-by: Michal Maslanka <michal@redpanda.com> (cherry picked from commit 5880248)
