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 delete instance on the controller node
* Then 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.

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.
