lib/rbtree.c: fix typo in comment of __rb_insert()
In case 1, it passes down the BLACK color from G to p and u, and maintains
the color of n. By doing so, it maintains the black height of the
sub-tree.
While in the comment, it marks the color of n to BLACK. This is a typo
and not consistents with the code.
This patch fixs this typo in comment.
