    sys/vfs/hammer: Fix possible panic with vfs.hammer.debug_general=0x4000
    
    bc996e6 needed to check NULL-elm case for node reblock
    when (vfs.hammer.debug_general & 0x4000) != 0.
    
    The above sysctl has 0 by default, so nothing will happen
    as long as keeping a default value when reblock starts.
