Subject: [PATCH] nvme: make config_item_type __ro_after_init

Make these __ro_after_init as they are only stored as a reference in the
ci_type field of a config_item structure during the init phase in the
function config_group_init_type_name. None of the fields of these
structures are modified after the init phase, so they can be
__ro_after_init.

Structures found using Coccinelle and changes done by hand.
