maple_tree: Fix off-by-one on append_entry

When appending an entry, ensure that the previous pivot is one less than
the desired range.

Don't subtraction coalesce from the slot calculation as that is now
taken into account within  _mas_add_slot_cnt itself.

Fix testing to kick out if mas_for_each is in a retry loop.
