I'm pretty sure it's more complicated than this patch (and the previous
one) - we already do free this at least in the case that "new =
kzalloc(...)" fails in cfg80211_bss_update().

Your Fixes: tag is also wrong, back then we didn't even have the dynamic
allocation of the IEs.

I'm dropping this patch and the other and will make a note to eventually
look at the lifetime issue here you point out, but if you want to work
on it instead let me know.
