    LinuxKPI: 802.11: remove ieee80211_node_get_txrate_dot11rate()
    
    net80211 ieee80211_node_get_txrate_dot11rate() does not yet support
    VHT and that means we get a lot of log lines when doing VHT for a
    debugging statement even if it's not active.
    Remove the calls to ieee80211_node_get_txrate_dot11rate() as with
    hw/fw based rate control (modern iwlwifi) they are pointless anyway
    as they are currently.

    (cherry picked from commit d1a37f280be46a707b42c3eca5f8b6a38ecf726b)
