[PATCH] maple_tree: Fix the error of mas->min/max in mas_skip_node()

[Peng Zhang]

The assignment of mas->min and mas->max is wrong. mas->min and mas->max
should represent the range of the current node. After mas_ascend()
returns, mas-min and mas->max already represent the range of the current
node, so we should delete these assignments of mas->min and mas->max.
