Fix coverity defects: CID 154617

CID 154617: Memory - illegal accesses (UNINIT)

The value here just needs to be initialized to make Coverity happy.
When dsize == 0, then value of daiter.iter_mapaddr is irrelevant. That
address won't be accessed, it's only used for some arithmetic. dsize
can be zero either if dabd is null, or if code column is longer than the
current data column.
