nvme: stop setting namespace gendisk device driver data

Since commit 1f4137e882c6 ("nvme: move passthrough logging attribute to
head"), we stopped using the namespace to hold the passthrough logging
enabled attribute. There is now nowhere now which looks up the gendisk dev
driver data, so stop setting it.

Incidentally, it would have been better to set this before adding the
disk.
