Title:
  The wrong default-prefixlen have not checked, when create a subnetpool

Status in neutron:
  Won't Fix

Bug description:
  In Newton environment.

  I create an unreasonable subnetpool, bacause the default-prefixlen(16)
  is less than the network number(24).But It can be created
  successfully.

  For example:
  #neutron subnetpool-create test_subnetpool --pool-prefix 10.0.0.0/24 --default-prefixlen 16
  Created a new subnetpool:

  When I using the subnetpool, It will be error.

  For example:
  #neutron net-create demo-net
  #neutron subnet-create demo-net --name demo-subnet --subnetpool test_subnetpool
  Failed to allocate subnet: Insufficient prefix space to allocate subnet size /16.
  Neutron server returns request_ids: ['req-99b5a7be-fbb1-4f00-8a89-5e3b7ce4041c']

  I think this subnetpool should not be created successfully in this
  situation.
