brcm63xx: mac80211.sh: use DFS workaround for AP
Use DFS workaround only for AP interface. In other case we hit strange problem:
- have wlX as a station
- have wlX.1 as a AP
Hostapd startup failed on wlX.1 while macaddr set IOCTL fail.
Interesting that we/hostapd can change/set mac address only when wl is down.
