Btrfs: avoid unnecessary bitmap search for cluster setup setup_cluster_no_bitmap() searches all the extents and bitmaps starting from offset. Therefore if it returns -ENOSPC, all the bitmaps starting from offset are in the bitmaps list, so it's sufficient to search from this list in setup_cluser_bitmap().
