BUG#39007 rpl_ndb.rpl_ndb_circular_2ch crashed in pushbuild

According to documenation:
http://dev.mysql.com/doc/refman/5.1/en/mysql-cluster-replication-issues.html

When setting up circular replication for clusters with different
SQL nodes in each cluster used as replication master and slave,
SQL nodes must not start with --log-slave-updates option. 

This patch fixed the test case by remove log-slave-updates 
configuration from test case configuration file.

mysql-test/suite/rpl_ndb/t/rpl_ndb_circular_2ch.cnf:
  remove option --log-slave-updates
mysql-test/suite/rpl_ndb/t/rpl_ndb_circular_2ch.test:
  ndbcluster only supports mixed or row binlog format
