Log message:
Checking the MIC early in ieee80211_recv_eapol() does not work for
message 2/4 of the 4-way handshake because the authenticator must
derive the PTK first (the MIC is computed using the KCK).
Move calls to ieee80211_eapol_key_check_mic() - and as a consequence
ieee80211_eapol_key_decrypt() - directly in the
ieee80211_recv_{group,4way}_msg*() functions.
Unconstify the first parameter since checking the MIC modifies the
frame. Remove ni->ni_ptk_ok field while i'm here.
