maple_tree: re-introduce entry to mas_preallocate() arguments

The current preallocation strategy is to preallocate the absolute
worst-case allocation for a tree modification.  The entry (or NULL) is
needed to know how many nodes are needed to write to the tree.  Start by
adding the argument to the mas_preallocate() definition.
