Revert "libipw: initiate cfg80211 API conversion"
This reverts commit b8ecd988b1.
Due to poor API call balancing by me, this commit not only broke ipw2200
if it can't find it's firmware, it broke ipw2100 basically anytime you
removed the module. At this point in the cycle, let's just put it back
to a sane state and try again next time...
