Subject: [PATCH] [v2] nvme-pci: disable write zeros support on specific SSDs

Like commit 5611ec2b9814 ("nvme-pci: prevent SK hynix PC400 from using
Write Zeroes command"), Micron has the same issue:
[ 6305.633887] blk_update_request: operation not supported error, dev
nvme0n1, sector 340812032 op 0x9:(WRITE_ZEROES) flags 0x0 phys_seg 0 prio class 0

So also disable Write Zeroes command on Micron.
