  Log:
    variable.c (autoload_sleep_done): avoid needless list_node init
    
    We do not need list_del_init in ensure callbacks, only list_del,
    since it can only ever be called after list_del_init in
    autoload_reset.  So avoid the needless re-initialization.
    
    * variable.c (autoload_sleep_done): s/list_del_init/list_del/
