    LinuxKPI: 802.11: fix field order in ieee80211_key_conf
    
    When adding the new field link_id to struct ieee80211_key_conf, it
    was erroneously placed at the end of the struct;  the zero-length
    (variable sized) array for the key always needs to stay last.
    Resort fields and add hopefully helpful comment to avoid the problem
    in the future.
