libwifi: broadcom: don't pass EAP frames to bridge
We should not pass EAP frames to the bridge.
Without the patch we fail GTK rekey for 4addr mode station:
- AP - backhaul bss
- STA - backhaul sta (4addr mode) Each time AP request GTK rekey we disconnect STA.
Newest kernel already handle this in mac80211, play correctly with control_port_protocol. So, no issue for mac80211 based drivers.
