[SPARK-18856][SQL] non-empty partitioned table should not report zero size
## What changes were proposed in this pull request?
In `DataSource`, if the table is not analyzed, we will use 0 as the default
value for table size. This is dangerous, we may broadcast a large table and
cause OOM. We should use `defaultSizeInBytes` instead.
## How was this patch tested?
new regression test
