Title:
  LoadBalancerCallbacks.get_ready_devices() returns incorrect set of
  devices

Status in OpenStack Quantum (virtual network service):
  Fix Released

Bug description:
  LoadBalancerCallbacks.get_ready_devices() incorrectly forms DB query that should select devices having pool and vip attached to it.
  Instead of inner join, query returns result of full join.

  As a result, lbaas agent receives devices (pool ids) without vip and
  makes rpc calls that fail on server side, producing stack traces on
  both ends.
