nvme-pci: refresh visible attrs for cmb attributes

commit e917a849c3fc317c4a5f82bb18726000173d39e6 upstream.

The sysfs group containing the cmb attributes is registered before the
driver knows if they need to be visible or not. Update the group when
cmb attributes are known to exist so the visibility setting is correct.
