Unfortunately the content of the new xfs_bmapi_update_map()

The -1 index values are just awful, even if we do know from
the logic that they're indexing non-negative offsets into the
underlying array.  I do think it's good that you encapsulated
this without changing the existing logic, but someday maybe
this function can be improved.
