nvme: move ns id info to struct nvme_ns_head
Move the namesapce info to struct nvme_ns_head, because it's the same
for all associated namespaces.
Note: with multipathing enabled the PI information is shared between all
paths. If a path is using a different PI configuration it will overwrite
the previous settings. This is obviously not correct and such
configuration will be rejected in future. For the time being we expect
a correctly configured storage.
