Fix int overflow when the struct column has null value

[JkSelf]

When struct has null value, the bitBuffer will identify rows with null values and not be nullptr in ArrowArray in native side. In Java side, if the bitBuffer is not null, it will be initialized to newBuffer with Integer.MAX_VALUE capacity here when import buffers. Then when calling the StructVector.setValueCount() method, the getValidityBufferValueCapacity will throw int overflow issue.

Yes. It seems this issue has been fixed and we can remove this change after upgrading arrow.
