[JFFS2] Correct handling of JFFS2_FEATURE_RWCOMPAT_COPY nodes.
We should preserve these when we come to garbage collect them, not let them get erased. Use jffs2_garbage_collect_pristine() for this, and make sure the summary code copes -- just refrain from writing a summary for any block which contains a node we don't understand.
