The backref code will look up the fs_root we're trying to resolve our indirect refs for, unfortunately we use btrfs_read_fs_root_no_name, which returns -ENOENT if the ref is 0. This isn't helpful for the qgroup stuff with snapshot delete as it won't be able to search down the snapshot we are deleting, which will cause us to miss roots. So use btrfs_get_fs_root and send false for check_ref so we can always get the root we're looking for.
