    wifi: cfg80211: Improve the documentation for NL80211_CMD_ASSOC_MLO_RECONF
    
    The existing documentation for the NL80211_CMD_ASSOC_MLO_RECONF
    does not clearly explain handling of link reconfiguration request
    results from the driver.
    
    Add documentation to explain that the command is used as an event to
    notify userspace about added links information, and that the existing
    NL80211_CMD_LINKS_REMOVED command is used to notify userspace about
    removed links information.
