nl80211: Update link bandwidth when receiving channel switch event

There is a chance that the driver has switched the channel width so we
should update the bandwidth, too, when receiving a channel switch event.
Otherwise, this may cause out of sync for bandwidth between i802_link
and hostapd_config.
