Subject: [PATCH] Fix convert function to support NVMe devices
This is adapted from the patch at
https://bugzilla.redhat.com/show_bug.cgi?id=1019660 , which is against
the now very old version of convert_system_partition_to_system_disk().
As such, it certainly not the right thing for upstream, but should
function for now.
Resolves: rhbz#1019660
