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
