[PATCH] ieee80211: Remove EAPOL debug

IEEE 802.11 code has no business touching payloads of EAPOL frames.
There are some EAPOL structures defined for debugging and these were
confusingly called EAP types which they are not. Let's just remove these
before someone else starts using them in the kernel.
