Staging: rtl8192u: remove a copy of 80211.h
We had a request to enable one of the realtek network drivers in staging in Fedora. After a quick lookover, I decided this wasn't such a great idea. In doing so though, I noticed we have 6 copies of ieee80211.h there now, Two drivers even have two copies of it. (Even worse, cleanups have been pointlessly happening to both files). The patch below removes one of them, which is asides from whitespace, identical afaics. With a change of filename to the #include, it all still compiles for me. A better fix would be to remove both, and have them use the core ieee80211 stuff, but this is at least a tiny step in the right direction.
