nvme-pci: add NVME_QUIRK_DISABLE_WRITE_ZEROES for Kingston OM3SGP4
The Kingston OM3SGP42048K2-A00 (PCI ID 2646:502f) firmware has a race condition when processing concurrent write zeroes and DSM (discard) commands, causing spurious "LBA Out of Range" errors and IOMMU page faults at address 0x0. The issue is reliably triggered by running two concurrent mkfs commands on different partitions of the same drive, which generates interleaved write zeroes and discard operations. Disable write zeroes for this device, matching the pattern used for other Kingston OM* drives that have similar firmware issues.
