dlm: avoid scanning unchanged toss lists Keep track of whether a toss list contains any shrinkable rsbs. If not, dlm_scand can avoid scanning the list for rsbs to shrink. Unnecessary scanning can otherwise waste a lot of time because the toss lists can contain a large number of rsbs that are non-shrinkable (directory records).
