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

As with the error handling for device_add() we follow the same
logic and just put the device so that cleanup is done via the
scsi_disk_release().

Thanks, would you like Jens to pick this up and the other scsi/sr patch
or are you taking it through your tree?

Didn't think I had the relevant add_disk() patch in my baseline tree but
it turns out I do. So I queued them up.

Thanks!
