Subject: [PATCH] brcm63xx: mac80211.sh: abort scan after reboot
Issue reproduced on DISC on wl0 when:
- set country GB channel 149
- 149 is non-DFS so scan should work while no CAC
After reboot scan on wl0 failed.
I suspect early (before we set country/channel) driver
start on DFS channel and run CAC and for some reason
stuck in that state.
