[SPARK-24257][SQL] LongToUnsafeRowMap calculate the new size may be
wrong
LongToUnsafeRowMap has a mistake when growing its page array: it blindly
grows to `oldSize * 2`, while the new record may be larger than `oldSize
* 2`. Then we may have a malformed UnsafeRow when querying this map,
whose actual data is smaller than its declared size, and the data is
corrupted.
