MDEV-32168: slave_error_param condition is never checked from the wait_for_slave_param.inc

Fix sporadic test failures in rpl.rpl_set_statement_default_master and
rpl.rpl_slave_load_tmpdir_not_exist. A race between START and STOP
SLAVE could leave an error condition that causes test failure after
MDEV-32168.
