btrfs: update stale comment for struct btrfs_delayed_ref_node::add_list

The comment refers to a list in the respective delayed ref head that no longer exists (ref_list), it was replaced with a rbtree (ref_tree) in commit 0e0adbc ("btrfs: track refs in a rb_tree instead of a list"). So update the stale comment to refer to the rbtree instead of the old list.
