nvme-pci: disable namespace identifiers for Qemu controllers
[ Upstream commit 66dd346b84d79fde20832ed691a54f4881eac20d ]
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.
