This late initialization breaks ligthnvm's core init since the sector
size (csecs) is used on the first init part to set the logical block size.

nvm_core_init -> blk_queue_logical_block_size(dev->q, dev_geo->c.csecs);

We can do do a nvme_nvm_revalidate and set this on the revalidation path
instead of simply updating the info as in nvme_nvm_update_nvm_info().
