Perform rate scaling properly when operating in an IBSS. Prior to this, the
5300 and 6205 devices (at least) would only transmit at
1 Mbps to other stations in an IBSS. This now allows transmission at HT rates.

Well - this would be called in other flows as well. For example, when we
receive a beacon that changes the bandwidth or alike. I am not sure we want to
re-init the rate scale data in this case, and more importantly, I am not sure
it will not race with the tx / tx_status path that updates / uses the rate
scale data.
