block: fix NULL pointer dereference in register_disk
commit 4d7c1d3fd7c7eda7dea351f071945e843a46c145 upstream.
If __device_add_disk-->bdi_register_owner-->bdi_register-->
bdi_register_va-->device_create_vargs fails, bdi->dev is still
NULL, __device_add_disk-->register_disk will visit bdi->dev->kobj.
This patch fixes that.
