[JFFS2] Fix writebuffer recovery in the first page of a block
For the case when nand_write_page fail with -EIO for the first page in an eraseblock, jffs2_wbuf_recover ends up producing a BUG in jffs2_block_refile as jeb->first_node is not yet set up (it's set up later in jffs2_wbuf_recover). This BUG is not really a bug; it's just jffs2_wbuf_recover calling jffs2_block_refile with the wrong second parameter. This patch takes care of this situation.
