Subject: [PATCH] pd: add error handling support for add_disk()
Git-commit: 3dfdd5f333bf16ec5057d508a574a3302ed84cfa
Patch-mainline: v5.16-rc1
References: jsc#PED-1183

We never checked for errors on add_disk() as this function
returned void. Now that this is fixed, use the shiny new
error handling.
