To update this for the history, in case someone else has this problem:

The subvolume was not listed by

  btrfs subvolume list

(presumably because the rsync had messed it up), but it was apparently
still marked as such in the filesystem metadata (even after a reboot).
I was able to clean up the mess via:

  btrfs subvolume delete /var/lib/lxc/container/rh65-dev/rootfs
  rm -rf /var/lib/lxc/container/rh65-dev/rootfs

and move the snapshot back in place to restore access to my original
instance.
