Subject: [PATCH] virtio_blk: add error handling support for add_disk()
References: jsc#PED-1183
Git-commit: dbb301f91fc855dccf9bc42fbc4281d89365906d
Patch-Mainline: v5.15-rc1
We never checked for errors on add_disk() as this function
returned void. Now that this is fixed, use the shiny new
error handling.
