koord-scheduler: remove allocated in filter hook

[KunWuLuan]

Currently, the resource reservation plugin doesn't subtract allocated resources from the reservepod after allocating resources to the pod, which will lead to fewer available resources on the nodes.

For example, a reservation reserved 2c on node and the reservation allocated 1c to pod. In this case available resource on node is allocated-2c instead of allocated-3c.
