Title:
  nova-compute got exception cause of residual instances

Status in OpenStack Compute (nova):
  New

Bug description:
  Description
  ===========
  Nova-compute got 'KeyError' exception when there is residual instance on the compute node.

  Steps to reproduce
  ==================
  * Stop nova-compute service on the compute node
  * Then nova reset-state instance on the controller node
  * Then nova delete instance on the controller node
  * Finally start nova-compute service on the compute node

  Expected result
  ===============
  nova-compute service can update its info to DB.

  Actual result
  =============
  nova-compute service got the 'KeyError' exception.
