When a bdev is registered, it is examined by the bdev modules before the bdev register even is notified. Examination may be asychronous, e.g. when the bdev module has to perform I/O on the new bdev. This causes a race condition where the bdev might be destroyed while examination is not finished. Then, once all modules have signaled that examination is done, `bdev_register_finished` makes an invalid access to the freed bdev pointer. To fix this, defer the unregistration until the examine is completed by opening a descriptor on the bdev.
