Call btrfs_cow_block while lowering tree level. When freeing root block of a tree, btrfs_free_extent' parameter 'ref_generation' is from root block itseft. When freeing non-root block, 'ref_generation' is from its parent. so when converting a non-root block to root block, we must guarantee its generation is equal to its parent's generation.
