Jason Gunthorpe 7adc0c1cfa iommufd: Reject non-zero data_type if no data_len is provided
Since the current design doesn't forward the data_type to the driver to
check unless there is a data_len/uptr for a driver specific struct we
should check and ensure that data_type is 0 if data_len is 0. Otherwise
any value is permitted.
