[HUDI-2573] Fixing double locking with multi-writers (#3827)

Browse Source 
- There are two code paths, where we are taking double locking. this was added as part of adding data table locks to update metadata table. Fixing those flows to avoid taking locks if a parent transaction already acquired a lock.
