[PATCH 5/7] maple_tree: the type of left subtree is already saved in bnode->type

[Wei Yang]

mast_sufficient()/mast_overflow() are only used in
mas_spanning_rebalance(). Before doing the check, mast_ascend() has
retrieved the left subtree type and stored in bnode->type.

So we can use the type in bnode->type directly to get minimum slot
count.
