The reason why BUG_ON exists is to catch bugs that happen, although
they Should Never Happen (tm) ;)

Precisely.

No really, this bug will never happen. This is function is merely a helper 
function which is called from interface removal code (where the interface 
*has* to be down) or from changing the interface type (which ensures that the 
interface is down first). There are an unlimited number of bugs which Should 
Never Happen. That doesn't mean we should start adding BUG_ONs for every 
single one of them. That gives some sort of protection against cosmic rays 
flipping bits, but down here on earth, it's bloat.
