[PATCH] nvme-pci: prevent SK Hynix PE8000 from using Write Zeroes command

For SK Hynix PE8000 WriteZerocommands exceed typical I/O MDTS
(Maximum Data Transfer Size) supported by the hardware. Which
intern fail and generate following erros :

nvme nvme0: I/O 0 QID 96 timeout, aborting
nvme nvme0: Abort status: 0x371
nvme nvme0: Shutdown timeout set to 15 seconds
nvme nvme0: 128/0/0 default/read/poll queues
nvme nvme0: I/O 0 QID 96 timeout, disable controller
nvme nvme0: I/O 0 QID 0 timeout, disable controller
nvme nvme0: Device shutdown incomplete; abort shutdown
nvme nvme0: failed to mark controller live state
nvme nvme0: Removing after probe failure status: -19

Firmware unable to complete any outstanding commands
due to lack of resources, therefore placing NVMe drive
in a condition that is unable to further process WriteZerocommands.

fixing by disabling Write zeroes.
