  ofproto: fix the bug of bucket counter is not updated

After inserting/removing a bucket, we don't update the bucket counter.
When we call ovs-ofctl dump-group-stats br-int, a panic happened.

Reproduce steps:
1. ovs-ofctl -O OpenFlow15 add-group br-int "group_id=1, type=select, selection_method=hash bucket=bucket_id=1,weight:100,actions=output:1"
2. ovs-ofctl insert-buckets br-int "group_id=1, command_bucket_id=last, bucket=bucket_id=7,weight:800,actions=output:1"
3. ovs-ofctl dump-group-stats br-int
