maple_tree: Rework mas_replace()

Drop ma_set_slot() and mte_set_slot() in favour of just setting the slot
value in the parent.  This is the only function using those two
functions and they are not necessary.

Drop check for replacing the node with itself as that doesn't happen -
confirmed by running the test suite with a BUG_ON instead of the swap.
