Public bug reported:

Description
===========
When vm is soft-deleted, we can not detach port from it. But when vm is shutoff, we can detach port.
VM in SOFT-DELETED and SHUTOFF status are the same status at the hypervisor level. The guest is shutdown. Why can't they do the same operation?

Steps to reproduce
==================
1) set reclaim_instance_interval > 0 to enable soft-delete
2) create an instance vm01
3) create a port port01 and then attach it to vm01
4) delete vm01
5) detach port01 from vm01

Expected result
===============
port01 can be detached successfully.

Actual result
=============
The detach operation failed.
