nvme: check the PRINFO bit before deciding the host buffer length
[ Upstream commit 4d6b1c95 ] 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. Signed-off-by:Revanth Rajashekar <revanth.rajashekar@intel.com> Signed-off-by:
