- Regression introduced by fix for Bug#23089566
  HA_NDBCLUSTER::OPEN_INDEXES MEMORY LEAK. The mysqld crash in a
  debug compile assert.

- Testcase created to show the problem, the debug time assert in
  release_indexes() removed to avoid since m_table poiunter is not
  really used by the function. It was just a way to detect if table
  is open or not.
