mac80211: clean up eapol frame handling/port control
This cleans up the eapol frame handling and some related code in the
receive and transmit paths. After this patch
* EAPOL frames addressed to us or the EAPOL group address are
always accepted regardless of whether they are encrypted or not
* other frames from a station are dropped if PAE is enabled and
the station is not authorized
* unencrypted frames (except the EAPOL frames above) are dropped if
drop_unencrypted is enabled
* some superfluous code that eth_type_trans handles anyway is gone
* port control is done for transmitted packets
