wifi: mac80211: fix unauthorised port check for encap offload

Browse source

The check in ieee80211_tx_dequeue() reads frame_control, addr1 and
addr2 out of the skb, but for encapsulation offload that's just a
random part of the ethernet addresses, so dropping depends on bits
in the destination address. This is obviously wrong.

Refactor the check and short-circuit for ethernet format frames,
it only needs the port-control flag check since those are locally
generated and not forwarded frames.
