[PATCH] nvme-pci: mark Lexar NM760 as IGNORE_DEV_SUBNQN

[Juraj Pecigos]

A system with more than one of these SSDs will only have one usable.
The kernel fails to detect more than one nvme device due to duplicate
cntlids.

before:

[    1.211080] nvme nvme0: 16/0/0 default/read/poll queues
[    1.216145] nvme nvme0: Ignoring bogus Namespace Identifiers
[    1.216261] nvme nvme1: Ignoring bogus Namespace Identifiers

Adding the NVME_QUIRK_IGNORE_DEV_SUBNQN quirk to resolves the issue.
