mac80211: Extend the rate control API with an update callback
The AP can switch dynamically between 20/40 Mhz channel width,
in which case we switch the local operating channel, but the
rate control algorithm is not notified. This patch adds a new callback
to indicate such changes to the RC algorithm.
Currently, HT channel width change is notified, but this callback
can be used to indicate any new requirements that might come up later on.
