[JFFS2] Reduce visibility of raw_node_ref to upper layers of JFFS2 code.
As the first step towards eliminating the ref->next_phys member and saving memory by using an _array_ of struct jffs2_raw_node_ref per eraseblock, stop the write functions from allocating their own refs; have them just _reserve_ the appropriate number instead. Then jffs2_link_node_ref() can just fill them in. Use a linked list of pre-allocated refs in the superblock, for now. Once we switch to an array, it'll just be a case of extending that array.
