Remember to also reset the last_dfs_cac_time when you receive a
RADAR_DETECTED event, as we discussed.  This will make sure we never
allow TX in DFS channels unless the DFS_MIN_CAC_TIME has passed since
detection started AND since the last radio signal was detected.

This will prevent the userspace from TXing illegally in DFS channels.
