MDEV-18300: ASAN error in Field_blob::get_key_image upon UPDATE with subquery
For single table updates and multi-table updates , engine independent statistics were not being
read even if the statistics were collected.
Fixed it, so when the optimizer_use_condition_selectivity > 2 then we would read the available
statistics for update queries.
