Fix for bug #31349: ERROR 1062 (23000): Duplicate entry '' for key 'group_key'
Problem: lying to the optimizer that a function (Item_func_inet_ntoa)
cannot return NULL values leads to unexpected results (in the case group
keys creation/comparison is broken).
Fix: Item_func_inet_ntoa::maybe_null should be set properly.
