Subject: nvme-pci: disable write zeroes on various Kingston SSD
Patch-mainline: v6.1-rc2
Git-commit: ac9b57d4e1e3ecf0122e915bbba1bd4c90ec3031
References: git-fixes
Kingston SSDs do support NVMe Write_Zeroes cmd but take long time to
process. The firmware version is locked by these SSDs, we can not expect
firmware improvement, so disable Write_Zeroes cmd.
