For BTRFS_SHARED_BLOCK_REF_KEY, its processing is straightforward, as we now the parent node bytenr directly. If the parent is already cached, or a root, call it a day. If the parent is not cached, add it pending list. This patch will just refactor this part into its own function, handle_direct_tree_backref() and add some comment explaining the @ref_key parameter.
