[SPARK-21312][SQL] correct UnsafeRow.writeToStream offsetInBytes
## What changes were proposed in this pull request?
Corrects offsetInBytes calculation in UnsafeRow.writeToStream. Known
failures include writes to some DataSources that have own SparkPlan
implementations and cause EXCHANGE in writes.
## How was this patch tested?
Extended UnsafeRowSuite.writeToStream to include an UnsafeRow over byte
array having non-zero offset.
