cfg80211: add some missing fall through annotations
There are talks about enabling -Wimplicit-fallthrough warnings in the mainline and it is already enabled in linux-next. Add all the missing annotations to prevent warnings when this happens. And in one case, remove the extra text from the annotation so that the compiler recognizes it.
