The exception could occur due to the existing delete for FilesetEntry
deleting based on volume ids, which would only match a filelist.
The bsIdsSubQuery would return BlocksetIds that should
be deleted and would delete from the FileLookup table.
FilesetEntry would then have a higher count of rows
than what would be returned by the LEFT OUTER JOINS on all of the
other tables in VerifyConsistency() since more rows had been deleted
from FileLookup.
To fix this when rows are deleted in FileLookup, use the associated metadata id
to delete from FilesetEntry and other tables based on the blockset id for the
metadata id.
Some existing delete statements were moved, none were deleted.
The existing FileLookup delete had the match on metadata id removed as
a blockset id does not equal a metadata id.
