    Multi-table delete that is optimized with QUICK_RANGE reports table
    corruption.
    
    DELETE statement must not use KEYREAD optimization, and sets
    table->no_keyread to 1. This was ignored in QUICK_RANGE optimization.
    
    With this fix QUICK_RANGE optimization honors table->no_keyread
    value and does not enable KEYREAD when it is requested.
