btrfs: add block-group tree to lockdep classes
The block group tree was not present among the lockdep classes. We could get potentially lockdep warnings but so far none has been seen, also because block-group-tree is a relatively new feature. CC: stable@vger.kernel.org # 6.1+ Signed-off-by: David Sterba <dsterba@suse.com>
