mariadb/mysql-test/main/join_cache.test
Oleg Smirnov 733852d4c3 BKA join cache buffer is employed despite join_cache_level=3 (flat BNLH) 
In the `check_join_cache_usage()` function there is a branching issue
where an accidental fall-through to BKA/BKAH buffers may occur, even
when the join_cache_level setting does not permit their use.

This patch corrects the condition to ensure that BKA/BKAH join caching
is only enabled when explicitly allowed by join_cache_level
