ath10k: Calculate correct peer PHY mode for VHT
The peer PHY mode for 11ac operation needs to be determined properly based on the channel bandwidth being used. Fix this so that the proper mode is given to the firmware. kvalo: earlier we used 11na-ht20 in STA mode for 11ac AP peer, this patch changes that to 11ac-vht80. I didn't notice any change in throughput in my tests, but nevertheless it's the right thing to do.
