    Prevent deadlock if fs_stateSave panics
    
    fs_stateSave can call ShutDownAndCore(PANIC) if it detects host list
    corruption. Right now this will deadlock the shutdown thread, since
    we're still holding a read lock on the FS state when we do so, and
    ShutDownAndCore will attempt to acquire a write lock. Do two things to
    make this a bit better:
    
     -- Unlock the FS state before calling fs_stateSave, sine we're no
     longer looking at the FS state (the 'state' in fs_stateSave refers to
     the host list and callback lists, not the state locked by
     FS_STATE_*LOCK)
    
     -- If ShutDownAndCore detects that it was called inside of
     ShutDownAndCore, skip shutting down the volume and host packages, since
     they have already been shut down
