    LinuxKPI: 802.11: stop ieee80211_start_tx_ba_session() if no HT supported
    
    rtw89(4) would constantly try to start a TX BlockACK session even if no
    HT or higher was available.  The only way to stop this (currently) is
    to return -EINVAL instead of any other error.
    
    Note: we should investigate if/when to call (*set_tid_config)() as that
    will also offer the ability to forbid BA.
