block: fix device_add_disk() kobject_create_and_add() error handling
Commit 83cbce957446 ("block: add error handling for device_add_disk /
add_disk") added error handling to device_add_disk(), however the goto
label for the kobject_create_and_add() failure did not set the return
value correctly, and so we can end up in a situation where
kobject_create_and_add() fails but we report success.
Fixes: 83cbce957446 ("block: add error handling for device_add_disk / add_disk")
