Removing subvolumes, and clobbering files didn't help, so I wound up
starting over. The first thing I did was create a base subvolume, and then
added a quota to it before creating subvolumes nested under it. Hopefully,
this will help. Unfortunately, with the way btrfs reports free space, it
will still be challenge to manage.
