Tatiana A. Nurnberg d7e7765b36 Bug#48295: explain extended crash with subquery and ONLY_FULL_GROUP_BY sql_mode ...

If an outer query is broken, a subquery might not even get set up.
EXPLAIN EXTENDED did not expect this and merrily tried to de-ref all
of the half-setup info.

We now catch this case and print as much as we have, as it doesn't cost us
anything (doesn't make regular execution slower).
