mac80211: Fix HT rate control configuration
Handling HT configuration changes involved setting the channel with the new HT parameters and then issuing a rate_update() notification to the driver. This behavior changed after the off-channel changes. Now, the channel is not updated with the new HT params in enable_ht() - instead, it is now done when the scan work terminates. This results in the driver depending on stale information, defaulting to non-HT mode always. Fix this by passing the new channel type to the driver.
