Fix for bug #9798: Rollup crash with InnoDB in setup_sum_funcs().
Disable mix/max group by optimization for queries with rollup for now.
Note: the actual bug was hidden; if this optimization works with rollup
queries we will have to change some code:
the problem is that we call the join->make_sum_func_list() function against
changed thd->mem_root (see SQL_SELECT::test_quick_select()) which creates some
items for rollup, then we free that mem_root, then we try to reuse (free) those
items.
