Thanks Christophe,

Of course, you found found this with your Coccinelle script so
technically it already silences a static checker warning... But I
ran into two list related use after frees yesterday so I'm definitely
going to create a Smatch warning which will trigger here as well.

I'm NOT going to add a if (if_list_is_devm()) exception because I feel
like that encourages subtle code and because devm_ lifetimes are
complicated.
