The reason DEVNAME is printed is because you're using the export
output format.
This behaviour was introduced in:

Apparently this behaviour is established since a very long time:
$ git describe dab33573876270fec7550252bcc29c34e9ad3889
v2.21-40-gdab3357
Possibly changing the output format now could be risky.
It's very unfortunate that Debian has lagged so long with updating
util-linux which means we notice these things so long after they
appeared.

Lets ask upstream if DEVNAME is considered a tag which should
be included in the tag filtering.... CCed.
