nvme-pci: add quirk for Memblaze Pblaze5 (0x1c5f:0x0555)
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.
