nvme: add a quirk to disable namespace identifiers

[ Upstream commit 00ff400e6deee00f7b15e200205b2708b63b8cf6 ]

Add a quirk to disable using and exporting namespace identifiers for
controllers where they are broken beyond repair.

The most directly visible problem with non-unique namespace identifiers
is that they break the /dev/disk/by-id/ links, with the link for a
supposedly unique identifier now pointing to one of multiple possible
namespaces that share the same ID, and a somewhat random selection of
which one actually shows up.
