remove_proc_subtree() doesn't work here as local->ddev has already
been removed, and NULLed out.  Use proc_remove() instead.

I would include an oops, however the machine I discovered this on has
a page 0 populated - so the symptoms are multiple 'wlan0' entries in
/proc/net/hostap.  This is probably a candidate for stable too.
