maple_tree: remove maple_big_node.parent
Patch series "Reduce the space to be cleared for maple_big_node", v2.
Found current code may clear maple_big_node redundantly.
First we define a field parent, which is never used. After removing this,
we reduce the size of memory to be cleared by memset.
Then mast_fill_bnode() clears part of the structure twice, since slot and
gap share some space. By clearing the whole structure, we can avoid this.
This patch (of 2):
The member parent of maple_big_node is never used.
Let's remove it which could reduce the number of space to be cleared on
memset.
