[PATCH] hostap: Fix EAPOL frame encryption

Fixed encrypted of EAPOL frames from wlan#ap interface (hostapd). This
was broken when moving to use new frame control field defines in
net/ieee80211.h. hostapd uses Protected flag, not protocol version
(which was cleared in this function anyway). This fixes WPA group key
handshake and re-authentication.
