Subject: [PATCH 1/1] Detail: fix --detail --export for uuid_zero
Mentioned commit (see Fixes) causes that devices with UUID
equal to uuid_zero was not recognized properly. For few devices
the first one was taken always, and the same information was
printed. It caused regression, when few containers were created,
symlinks were generated only for the first one.
Add checking if uuid is uuid_zero and, if yes, use devname to
differentiate devices.
Fixes: 60c19530dd7c ("Detail: remove duplicated code")
