Christoph Hellwig 87dd813bd2 nvme-pci: disable namespace identifiers for Qemu controllers
[ Upstream commit 66dd346b84 ]

Qemu unconditionally reports a UUID, which depending on the qemu version
is either all-null (which is incorrect but harmless) or contains a single
bit set for all controllers.  In addition it can also optionally report
a eui64 which needs to be manually set.  Disable namespace identifiers
for Qemu controlles entirely even if in some cases they could be set
correctly through manual intervention.
