Public bug reported:

Description
===========
Restarting nova-compute with queued migrations creates a split-brain between instance status and migration status.

Steps to reproduce
==================
1. Have live migration queued.
2. Restart nova-compute.

Expected result
===============
Instance remains MIGRATING and migration remains queued.

Actual result
=============
Instance becomes ACTIVE, migration remains queued, but can no longer be aborted - abort returns a 409 instead.

Environment
===========
Originally reported on OSP 16.2, should still affect master.
