commit 46320a6acc4fb58f04bcf78c4c942cc43b20f986 upstream.

In the second iteration of trace_selftest_ops(), the error goto label is
wrong in the case where trace_selftest_test_global_cnt is off. In the
case of error, it leaks the dynamic ops that was allocated.

Fixes: 95950c2e ("ftrace: Add self-tests for multiple function trace users")
