When we get empty batch, getPayloadByteCount will throw out of bounds
exception if the underlying method tries to read the value vector for index 0
i.e. when it is trying to read offset vector. I added the check in those
methods and removed here.
I still have to retain the check here for the case when we are trying to
read the offset vector.
