This patch removes a check in ifconfig which disables HT/40 channels
on frequency bands with DFS. All Atheros chipsets >= AR9001 support
radar event detection on HT40 extension channels.
This should be a chipset specific item rather than enforced in the
regulatory domain database.
In addition, it's irrelevant for STA mode, as the radar detection is
done by the access point, not the STA.
