    libafs: reset global icl set pointers on shutdown
    
    Avoid panicking when an icl tracing function is called after
    shutdown_icl.
    
    There is a window during shutdown in which pioctls can be requested
    after the shutdown_icl is issued. Reset the global icl set pointers
    so tracing is disabled after the shutdown_icl, instead of using
    pointers to freed memory.
    
    Removed the unneeded afs_icl_FindSet calls and use the global
    pointers which were set during the initialization.
