MDEV-30651: Assertion `sel->quick' in make_range_rowid_filters
The optimizer deals with Rowid Filters this way: 1. First, range optimizer is invoked. It saves information about all potential range accesses. 2. A query plan is chosen. Suppose, it uses a Rowid Filter on index $IDX. 3. JOIN::make_range_rowid_filters() calls the range optimizer again to create a quick select on index $IDX which will be used to populate the rowid filter. The problem: KILL command catches the query in step #3. Quick Select is not created which causes a crash. Fixed by checking if query was killed. Note: the problem also affects 10.6, even if error handling for SQL_SELECT::test_quick_select is different there.
