[SPARK-9973] [SQL] Correct in-memory columnar buffer size
The `initialSize` argument of `ColumnBuilder.initialize()` should be the
number of rows rather than bytes. However `InMemoryColumnarTableScan`
passes in a byte size, which makes Spark SQL allocate more memory than
necessary when building in-memory columnar buffers.

Closes #8189 from viper-kun/errorSize.
