Description:
The test case perfschema.dml_mutex_instances is not reliable:
it assumes LOCKED_BY_THREAD_ID is always NULL, which may not be the case.

How to repeat:
See spurious failures in PB2.

      Bug#50596 Spurious test failures in perfschema.dml_mutex_instances
      
      Fixed the dml_mutex_instances and dml_rwlock_instances to be more reliable.
      In particular, the tests may not assume a mutex or rwlock is never locked.
