mds: fix CDir::log_mark_dirty()

CDir::log_mark_dirty() moves dirfrag to current log segment's dirty
dirfrag list, but it does not submit any log event. Old log segments
(that include events which dirty the dirfrag) may get expired before
the dirfrag gets committed. If MDS crashes, the changes in expired
log segments get lost.
