maple_tree: introduce __mas_set_range()
mas_set_range() resets the node to MAS_START, which will cause a re-walk
of the tree to the range. This is unnecessary when the maple state is
already at the correct location of the write. Add a function that only
sets the range to avoid unnecessary re-walking of the tree.
