FWIW, I tried to reproduce the oops in the hope that I could confirm
a fix.  But I failed. The netdev is successfully deregistered on my
laptop no matter what I do. Tested v6.3 and current net/main, and
tried different tricks to change probe timing.

Guess this is timing sensitive enough that it only shows up on certain
systems.

So we will need the reporter to chime in.
