[JFFS2][XATTR] Handling the duplicate JFFS2_NODETYPE_XATTR node cases.
When jffs2_sum_process_sum_data() found a JFFS2_NODETYPE_XATTR which has duplicate xid and older version, an error was returned without appropriate process. In the result, mounting filesystem is failed. This patch fix this problem. If jffs2_setup_xattr_datum() returned -EEXIST, the caller marks this node as DIRTY_SPACE().
