MDEV-16957: Server crashes in Field_iterator_natural_join::next upon 2nd execution of SPbb-5.5-MDEV-16957
The problem was that join_columns creation was not finished due to error of notfound column in USING, but next execution tried to use join_columns lists.
Solution is cleanup the lists on error. It can eat memory in statement MEM_ROOT but it is an error and error will be fixed or statement/procedure removed/altered.
