Sergei Petrunia 6a89f346de MDEV-25858: Query results are incorrect when indexes are added ...

If test_if_skip_sort_order() decides to use an index to produce required
ordering,  it should disable "Range Checked for each record" optimization.

This is because Range-Checked-for-each-record may decide to use an index
(or an index_merge) which will not produce the required ordering.
