nvme: check the PRINFO bit before deciding the host buffer length
According to NVMe spec v1.4, section 8.3.1, the PRINFO bit and
the metadata size play a vital role in deteriming the host buffer size.
If PRIFNO bit is set and MS==8, the host doesn't add the metadata buffer,
instead the controller adds it.
