We never checked for errors on add_disk() as this function returned void. Now that this is fixed, use the shiny new error handling. Since nvdimm/blk uses devm we just need to move the devm registration towards the end. And in hindsight, that seems to also provide a fix given del_gendisk() should not be called unless the disk was already added via add_disk(). The probably of that issue happening is low though, like OOM while calling devm_add_action(), so the fix is minor. We manually unwind in case of add_disk() failure prior to the devm registration.
