MDEV-30586 DELETE with aggregation in subquery of WHERE returns bogus error
The parser code for single-table DELETE missed the call of the function
LEX::check_main_unit_semantics(). As a result the the field nested level
of SELECT_LEX structures remained set 0 for all non-top level selects.
This could lead to different kind of problems. In particular this did not
allow to determine properly the selects where set functions had to be
aggregated when they were used in inner subqueries.
