Subject: [PATCH AUTOSEL 6.0 31/34] nvme-pci: disable write zeroes on various Kingston SSD

From: Xander Li <xander_li@...gston.com.tw>

[ Upstream commit ac9b57d4e1e3ecf0122e915bbba1bd4c90ec3031 ]

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.
