Fix potential double-free in QSqlCachedResult::cleanup()
If d->sql is non-null, it gets freed; later in the same function, it
gets reallocated, unless the query is empty, in which case the
now-freed value was still recorded, so that later clean-up might find
it and mistakenly think it needs to be freed again. Clear when freeing.
Pick-to: 6.2 6.1
