[PATCH] nvme-pci: add quirk for Memblaze Pblaze5 (0x1c5f:0x0555)

[Tao Jiang <tanroame.kyle@gmail.com>]

The Memblaze Pblaze5 NVMe device (PCI ID 0x1c5f:0x0555)
is detected as a controller on recent kernels (tested on 5.15.85
and 6.8.4), but no namespace is exposed.

Tools like lsblk and fdisk do not report any block device.

dmesg shows:
  nvme nvme0: missing or invalid SUBNQN field.

The device works correctly on older kernels (e.g. 4.19), suggesting
a compatibility issue with newer namespace handling.

This indicates the device does not properly support the
Namespace Descriptor List feature.

Applying NVME_QUIRK_NO_NS_DESC_LIST allows the namespace to be
discovered correctly.
