Public bug reported:

Description
===========
Volume detaching incorrectly fails when shadow VM adapter type is IDE and instance VM adapter type is not IDE.

Steps to reproduce
==================
* Get a volume with shadow VM adapter type IDE
* Get a server with non-IDE adapter type
* Attach the volume to the server
* Attempt to detach the volume from the server (while server is powered-on)

Expected result
===============
Detach must be successful since adapter type on server instance VM is not IDE hence no need for the instance VM to be powered-off.

Actual result
=============
Detach failed complaining about IDE not supporting hotplug. The incorrect logic is here https://github.com/openstack/nova/blob/766d13218763f43ba91c2a15adff438a0dd84e37/nova/virt/vmwareapi/volumeops.py#L519-L528.

Environment
===========
1. Exact version of OpenStack you are running.
Queens

2. Which hypervisor did you use?
vSphere 6.5

     Importance: Undecided
