[SPARK-12589][SQL] Fix UnsafeRowParquetRecordReader to properly set the row
length.
The reader was previously not setting the row length meaning it was wrong
if there were variable
length columns. This problem does not manifest usually, since the value in
the column is correct and
projecting the row fixes the issue.
