Peng Zhang 64891ba3e5 maple_tree: add a fast path case in mas_wr_slot_store()
When expanding a range in two directions, only partially overwriting the
previous and next ranges, the number of entries will not be increased, so
we can just update the pivots as a fast path. However, it may introduce
potential risks in RCU mode, because it updates two pivots. We only
enable it in non-RCU mode.
