gfs2: initialize transaction tr_ailX_lists earlier
Since transactions may be freed shortly after they're created, before a log_flush occurs, we need to initialize their ail1 and ail2 lists earlier. Before this patch, the ail1 list was initialized in gfs2_log_flush(). This moves the initialization to the point when the transaction is first created.
