[JFFS2] Introduce jffs2_link_node_ref() function to reduce code duplication
The same sequence of code was repeated in many places, to add a new struct jffs2_raw_node_ref to an eraseblock and adjust the space accounting accordingly. Move it out-of-line. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
