    wifi: mt76: mt7915: fix power-limits while chan_switch
    
    [ 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.

    Fixes: f1d962369d56 ("mt76: mt7915: implement HE per-rate tx power support")
