[ Upstream commit 4d6b1c95b974761c01cbad92321b82232b66d2a2 ] 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.
