lib/rbtree.c: fix typo in comment of ____rb_erase_color
In Case 3 of `sibling == parent->rb_right':
Right rotation will not change color of sl and S in the diagram
(i.e. should not change "sl" to "Sl", "S" to "s")
In Case 3 of `sibling == parent->rb_left':
(p) (p)
/ \ / \
S N --> sr N
/ \ /
Sl sr S
/
Sl
This is actually left rotation at "S", not right rotation.
In Case 4 of `sibling == parent->rb_left':
(p) (s)
/ \ / \
S N --> Sl P
/ \ / \
sl (sr) (sr) N
This is actually right rotation at "(p)" + color flips, not left
rotation + color flips.
