This commit adds NVME_QUIRK_BOGUS_NID for device [1cc4:6a14], the
Shenzhen Unionmemory Information System Ltd. RPEYJ1T24MKN2QWY PCIe
4.0 NVMe SSD 1024GB (DRAM-less), which can be found on many Lenovo
notebooks. This SSD produces all-zero nguid.

Other SSDs manufatured by Shenzhen Unionmemory Information System
Ltd are likely to face similar issues, but I currently have no
device to test.
