This appears to be as a result of https://review.opendev.org/#/c/697694/
*and* a race within the test resulting in the delete_race method above
not always being used with each run of the test.

Steps to reproduce
==================

* $ tox -e functional-py36
nova.tests.functional.regressions.test_bug_1831771.TestDelete.test_delete_during_create

Expected result
===============

delete_race should always run and the test should pass.

Actual result
=============

delete_race either isn't called with the test then passing or it is and
the test fails.


Environment
===========
1. Exact version of OpenStack you are running. See the following
  list for all releases: http://docs.openstack.org/releases/

   master - b3e14931d6aac6ee5776ce1e6974c75a5a6b1823

2. Which hypervisor did you use?
   (For example: Libvirt + KVM, Libvirt + XEN, Hyper-V, PowerKVM, ...)
   What's the version of that?

   N/A

2. Which storage type did you use?
   (For example: Ceph, LVM, GPFS, ...)
   What's the version of that?

   N/A

3. Which networking type did you use?
   (For example: nova-network, Neutron with OpenVSwitch, ...)

   N/A
