Hence, its caller, damon_set_region_biggest_system_ram_default(), was also not supporting addr_unit. The previous commit has updated the inner function to support addr_unit. There is no more reason to not support addr_unit on damon_set_region_biggest_system_ram_default(). Rather, it makes unnecessary inconsistency on support of addr_unit. Update it to receive addr_unit and handle it inside.
