slave node killed himself.
Problem:- If we try to delete table with foreign key and table whom it is
referring with wsrep_slave_threads>1 then galera tries to execute both
Delete_rows_log-event in parallel, which should not happen.
Solution:- This is happening because we do not have foreign key info in
write set. Upto version 10.2.7 it used to work fine. Actually it happening
because of issue in commit 2f342c4. wsrep_must_process_fk has changed to
make it similar to original condition.
