  lxc-destroy fails on btrfs subvolumes

Status in lxc package in Ubuntu:
  Fix Released
Status in lxc source package in Vivid:
  Fix Released
Status in lxc source package in Wily:
  Fix Released

Bug description:
  $ sudo lxc-destroy -n adt-vivid
  [sudo] password for martin: 
  lxc_container: utils.c: _recursive_rmdir_onedev: 147 _recursive_rmdir_onedev: failed to delete /srv/lxc/adt-vivid/rootfs/var/lib
  lxc_container: utils.c: _recursive_rmdir_onedev: 147 _recursive_rmdir_onedev: failed to delete /srv/lxc/adt-vivid/rootfs/var
  lxc_container: utils.c: _recursive_rmdir_onedev: 147 _recursive_rmdir_onedev: failed to delete /srv/lxc/adt-vivid/rootfs
  lxc_container: lxccontainer.c: container_destroy: 2050 Error destroying rootfs for adt-vivid
  Destroying adt-vivid failed

  This is because the container rootfs has a btrfs subvolume:

  ID 557 gen 97073 top level 266 path @srv/lxc/adt-
  vivid/rootfs/var/lib/machines

  After "sudo btrfs subvolume delete /srv/lxc/adt-
  vivid/rootfs/var/lib/machines" I can remove the container.
