[PATCH 02/10] pktcdvd: add error handling support for add_disk()

From: Luis Chamberlain
Date: Wed Sep 01 2021 - 17:02:07 EST


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

The out_mem2 error label already does what we need so
re-use that.
