Public bug reported:

If API times out on a RPC during the processing of a migrate_server it
does not revert the task_state back to NULL before or after sending the
error response back to the user. This can prevent further API operations
on the VM and leave a good VMs in non-operable state with the exception
of perhaps a delete.

This is one possible reproducer. I'm not sure if this is always true,
and I'd appreciate if someone else confirm it.

1. Somehow make RPC requests hang
2. Issue a live migration request
3. The call should return an HTTP error (409 perhaps)
4. Check VM. It should be in a good state but the task_state stuck in 'migrating'
