Title:
  During subnet-update, allocation_pools used before being validated

Status in neutron:
  Fix Released

Bug description:
  During the processing of a subnet-update request, neutron uses the
  specified allocation_pools to determine if the gateway IP is in that
  specified pool [1] prior to that incoming allocation_pools property
  ever being validated [2].

  Validation of the incoming allocation_pool should be done before that property  is used.
