Fix PeerKey 4-way handshake

The earlier changes to buffer EAPOL frames when not associated to avoid
race conditions (especially commit
3ab35a6603 but maybe something even before
that) broke PeerKey 4-way handshake. Fix this by using a separate check
before the race condition workaround to process PeerKey 4-way handshake
EAPOL-Key messages differently.
