MNT-22385 Cmis query GetTotalNumItems is returning wrong value (#504)

* Changes made to correct the value of totalItems when performing a TMDQ

* Fixes after review

- Slight change was made to NodePermissionAssessor to log when permission
  limits are exceeded

* Now pre-computing maxPermissionChecks value as per review suggestion

(cherry picked from commit cb636d1140)
