Chisheng Chen 3dfd79cc87 lib/rbtree.c: fix the example typo ...

Replace `sr` with `Sr`.  The condition `!tmp1 || rb_is_black(tmp1)`
ensures that `tmp1` (which is `sibling->rb_right`) is either NULL or a
black node.  Therefore, the right child of the sibling must be black, and
the example should use `Sr` instead of `sr`.
