More "todo", but this was indeed missing. I have addressed it in my new
versions in the mac80211-next/wip branch.

Well, the first was a leftover from before we even had an explicit IBSS
join operation -- now the (default) channel is just checked when you try
to join an IBSS, so the code in the first hunk has truly been
unnecessary for quite a while.
The second hunk ... similar story, it should be set whenever we first
use the interface by starting AP, joining IBSS or connecting to an AP or
mesh or whatever else could happen. So I think it should be safe.
