[Bug 1776958] Re: error creating lxdbr0.
This is happening again with Focal and Groovy:

=============================================
So the cleanup code runs, but for some reason fails to delete the
bridge. I tried running:
lxd init --auto --storage-backend=dir ; lxc network delete lxdbr0
--force-local
in a fresh Focal LXD container and it works (deletes lxdbr0), so I can't
tell where the problem is yet.

The integration test case tests/cloud_tests/testcases/modules/lxd_bridge.py
is demonstrates this failure on cosmic. It currently only occurs on
cosmic but will occur anywhere with lxd 3.1.0.
