Log Message:
If ifile blocks were written before dirops were complete, and then the
system crashed, inodes could be allocated that were not referenced.  (Though
not a serious problem, it evidences itself in phase 4 of fsck_lfs.)  Fix
this by marking if_daddr with UNASSIGNED before the inodes are actually
written; at mount time the ifile is checked for UNASSIGNED entries and
any that are found are linked back into the free list.  (The latter
functionality should move into the roll-forward agent when it materializes.)
