Davis Mosenkovs 82d0a11424 mac80211: fix memory corruption in EAPOL handling 
Commit e3d4030498 ("mac80211: do not accept/forward invalid EAPOL
frames") uses skb_mac_header() before eth_type_trans() is called
leading to incorrect pointer, the pointer gets written to. This issue
has appeared during backporting to 4.4, 4.9 and 4.14.

Fixes: e3d4030498 ("mac80211: do not accept/forward invalid EAPOL frames")
