Review comment:
This is useless, because the previous `setNull` has allowed `anyNull` to
return to true.
How about add a test:
```
int numFields = 80;
for (int i = 0; i < numFields; i++) {
BinaryRow row = new BinaryRow(80);
BinaryRowWriter writer = new
BinaryRowWriter(row);
assertFalse(row.anyNull());
writer.setNullAt(i);
assertTrue(row.anyNull());
}
```
