It's a harmless error during teardown of a nwfilter rule - the tap
device used for dhcp snooping has already been removed, and part of the
teardown tries to use it. However, the code does do the right thing if
the tap device no longer exists, it just happens to needlessly complain
in the process.

There is actually a patch to eliminate this complaint, sent to the
upstream libvirt list last month by the main nwfilter author (Stefan
Berger from IBM). I ACKed the patch soon after he sent it, but for some
reason he didn't push it. I asked him in IRC awhile ago if he wanted me
to push it for him, but he logged off before replying, so I'll send him
mail about it.
