Subject: [NET_SCHED 06/09]: sch_ingress: remove unnecessary ops

commit c96158287d0c87fc3e4d005ce8bf2c778a5c2cb6

    [NET_SCHED]: sch_ingress: remove unnecessary ops
    
    - ->reset is optional
    - sch_api provides identical defaults for ->dequeue/->requeue
    - ->drop can't happen since ingress never has a parent qdisc
