btrfs: add block-group tree to lockdep classes
commit 1a1b0e729d227f9f758f7b5f1c997e874e94156e upstream.
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.
