From: Gopal Tiwari <gtiwari@redhat.com>

[ Upstream commit 7ee5c78ca3895d44e918c38332921983ed678be0 ]

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

[ 6.274554] nvme nvme1: Duplicate cntlid 33 with nvme0, rejecting
[ 6.274566] nvme nvme1: Removing after probe failure status: -22

Adding the NVME_QUIRK_IGNORE_DEV_SUBNQN quirk to resolves the issue.
