[ Upstream commit 6c0570bc21ec2073890aa252c8420ca7bec402e4 ]
If user changes the channel without completely disabling the interface the txpower_sku values reported track the old channel the device was operating on. If user bounces the interface the correct power tables are applied.
mt7915_sku_group_len array gets updated before the channel switch happens so it uses data from the old channel.
